Abstract: تم تصميم الدراسة الحالية للتخلص من عقاري الباراسيتامول والبروكائين باستخدام الاشعة الفوق بنفسجية وبوجود اوكسيد الزنك كعامل مساعد، حيث سلطت الدراسه الضوء على اهمية كل من الضوء والعامل المساعد كعوامل اساسيه في التفكك الضوئي المحفز لكلا الدوائين.تضمنت الدرا | The current study is designed to treat the paracetamol and procaine by using UV light and ZnO as catalyst. This study explains the importance of the UV light and catalyst as a basic factors in the photocatalytic degradation for both paracetamol and procaine drugs. The study includes the measure of the rate of photocatalytic oxidation by measuring the absorbance of samples of aqueous solution for both drugs which is treated by UV light and ZnO. These absorbance are compared with the initial drug's absorbance. Some parameters which are effected on the rate of photocatalytic oxidation are studied in present research such as the amount of catalyst, initial concentration for the drug's solution, pH and the temperature for the drug's solution. The results show that the photocatalytic oxidation reaction for the paracetamol and procaine obey pseudo - first order according to the Langmuir - Hinshelwood relationship, and also it is found that the photoctalytic oxidation rate fits positively with the increase of the catalyst weight until the weights of ZnO equal to 0.025 g and 0.1 g are considered the optimum weights for paracetamol and procaine respectively where the best photocatalytic degradation is happened. So after these values, the photocatalytic degradation rate is decrease or stablized with the increase of the catalyst weight. In addition, the initial concentration increase for both drugs leads to reduce degradation rate. Also this study is found the increase of pH of reaction solution for both drugs has a positive effect represented by increasing the degradation rate until the pH 8 and 4 are the best acidic function of the paracetamol and procaine respectively. Regarding the change of the temperature has a little effect on the rate of photocatalytic degradation and it was noticed that the reaction rate increases with the increase of temperature. Activation energy is calculated according to the Arrhenius plot of lnK vs. 1/T, the slop of linear plot is equal to ( - Ea/R). Activation energy was found equal to 7.96 KJ. mol - 1 for paracetamol and 8.71 KJ. mol - 1 for procaine. The thermodynamic functions are calculated in current study for each drug and the results for paracetamol are as following : ?G = 63.61 ± 2.85 KJ.mol - 1?H = 5.40 ± 0.13 KJ.mol - 1?S = - 0.189 KJ.K - 1.mol - 1And the results of procaine are as following : ?G = 63.43 ± 2.81 KJ.mol - 1 ?H = 6.15 ± 0.13 KJ.mol - 1?S = - 0.186 KJ.K - 1.mol - 1The results of the suggested mechanism of degradation are shown that the final products for degradation are CO2, H2O and mineral acids.

Abstract: تم تحضير مركبات نانو مغناطيسية جديدة باستخدام الكوليستيرول والسلفادايزين مع اوكسيد الحديد المغناطيسي. حضرت هذه المركبات باستعمال طريقة الترسيب المشترك لاوكسيدي الحديد الثنائي والثلاثي ومن ثم ربطه بالحامض بطريقة فوق الاشباع. تم تشخيص المركبات المحضرة بالطر | Two new magnetic nanoparticles (MNPs) were prepared using magnetic iron oxides with cholesterol and sulfadiazine. These compounds were prepared by iron oxide (II and III) co - precipitation, and then the prepared MNP were incubated with cholesterol and sulfadiazine. The synthesized compounds were identified using multiple techniques, including transmission electron microscopy, scanning electron microscopy, diffractive light scattering, and thermogravimetric analysis. Results demonstrated the formation of new magnetic nanoparticles, namely, MNP@Cholesterol and MNP@Sulfadiazine. The interaction between the prepared MNPs and xanthine oxidase (XO) was evaluated as a potential method for the inhibition of the enzymatic activity. The inhibition of XO is an important issue to reduce the formation of uric acid, which is responsible for gout and kidney stone formation. Another potential application is the extraction of the XO enzyme from biological fluids, such as blood, or the immobilization of XO on the surfaces of MNPs as a new application of these insoluble particles.The interaction studies involved the incubation of XO solution with the suspension of prepared MNPs using XO solutions with different concentration and fixed MNP mass. The adsorption studies of XO on MNPs showed that the prepared MNPS can extract suitable amounts of XO from a solution. Slight differences in the XO quantities adsorbed on different MNPs were found. Adsorption isotherms followed the Sips equation, indicating slight heterogeneity in the adsorption active forces on MNPs. Circular dichroism study of the XO adsorption on the prepared MNPs showed significant changes in the secondary structures, namely, reduction of the ? - helix structure. Furthermore, fluorospectrophotometric studies showed changes in the tertiary structure of the XO caused by the interaction with the active sites of the prepared MNPs. The study of the inhibition of XO activity by the prepared MNPs showed mixed inhibition as a result of the changes in the original XO enzyme after interaction with the surfaces. Magnetic Fe3O4 showed the highest inhibition activity, followed by MNP@Sulfadiazine and MNP@Choleterol - XO.

Abstract: Corrosion and corrosion protection of carbon steel (C.S) alloy in seawater (3.5% NaCl) was achieved in this thesis. Three types of nanoparticles (NPs) were used to protect C.S the first silicon carbide (SiC), second alumina (Al2O3) and the third zirconium oxide (ZrO2) nanoparticles (NPs). Electrophoretic deposition (EPD) technique was applied to coating the C.S surface. Different polyacrylic acid (PAA) percentage (0.1 - 1)% were added to the suspension solution of coating by the three types of NPs, to improve the protection efficiency (PE%) for the coated C.S surfaces.The corrosion rate with respect to uncoated and coated C.S with the three above NPs were measured. Different corrosion parameters were obtained; corrosion current density (icorr), corrosion potential (Ecorr), cathodic and anodic Tafel slopes (bc,ba), protection efficiency (PE%), polarization resistance (Rp) and the surface porosity (P%). The effect of temperatures (298 - 328)K on the corrosion of uncoated and coated C.S by the three NPs in presence and absence of PAA were also investigated and therefore activation energy (Ea) and preexponential factor (A) were calculated. Thermodynamic parameters ?G, ?H and ?S for all corrosion processes were obtained. Coated C.S were analysed using atomic force microscopy (AFM) to detect the morphology of surface and the particles size of coat layers which range from 60 - 103 nm, which greater than thestarting particles.The corrosion current densities (icorr) were increased generally with increasing temperatures for all cases and icorr reduced after coated C.S by different NPs in absence and presence PAA, therefore icorr reduced from 168.88 ?A.cm - 2 to 19.45, 28.71 and 30.2 ?A.cm - 2 for C.S coated by SiC, ZrO2 and Al2O3 respectively at 298K.While the Ecorr shifted to more active potential after coated by different NPs excepting when C.S coated by SiC in presence of (0.25%) PAA in coating solution suspension where Ecorr shifted to noble direction. The protection efficiency (PE%) of all coated C.S in absence and presence of PAA showed noteworthy degree of enhancement and the PE% ranged between (85 to 99.65)% for SiC , (69 to 91)% for ZrO2 and (77 to 87.9)% for Al2O3. The surface porosity (P%) were increased with increasing temperatures for all cases. The activation energy (Ea) values for the corrosion of coated C.S by different NPs lead to higher values than Ea for uncoated C.S and the highest value was (71.936) kJ.mol - 1 obtained when C.S coated by SiC in presence of (0.25%) PAA. The free energy (?G) Values for the corrosion of coated C.S generally more negatively than uncoated and the values of enthalpy (?H) for the corrosion of coated C.S by ZrO2 and Al2O3 were less negatively than uncoated C.S while coated C.S by SiC lead to more negatively ?H values.
