Abstract:
This study contained ageneral introduction about the Ion - Selective electrodes and ageneral introduction about Schiff's Base and the determination of Diphenhydramine Hydrochloride (DPH) and Phenylephrine Hydrochloride (PEH) and Metoclopramide Hydrochloride (METO) and Metformin Hydrochloride (METF ) drugs using new methods applying potentiometric (the first part) and using Schiff's Base as ionophor In ISES membranes ( the second part).The first part includes construction of membrane selective electrodes for DPH and PEH drugs based on complexation of drugs with Ammonium Reinckate (AR) and Phospho Molybdic acid (PMA) as an active substance using Di - n - Butyl phthalate (DBPH) as a plasticizers , poly vinyl chloride was used as a matrix for all electrodes.The Characters of each electrode were as follow : 1. For the Diphenhydramine - Ammonium Reinckate (DP - AR) electrode using (DBPH) as a plasticizers, the optimum condition were (4.5 - 6.5), (20 - 30?C), 10 - 2 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29.40) mv/decade, correlation coefficient r= 0.9971, detection limit (8.88x10 - 7 M) and life time of the electrode was 34 days.2. For the Diphenhydramine - Phospho Molybdic acid (DP - PMA) electrode using (DBPH) as a plasticizers, the optimum condition were (4.5 - 6.5), (20 - 30 ?C), 10 - 4 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29. 90) mv/decade, correlation coefficient r= 0.9960, detection limit (6.8x10 - 8 M )and life time of the electrode was 40 days.3. For the Phenylephrine - Ammonium Reinckate (PE - AR) electrode using (DBPH) as a plasticizers, the optimum condition were (5 - 6), (25 - 30 ?C), 10 - 3 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29.8) mv/decade, correlation coefficient r= 0.9990, detection limit (2.22x10 - 7 M) and life time of the electrode was 24 days.4. For the Phenylephrine - Phospho Molybdic acid (PE - PMA) electrode using (DBPH) as a plasticizers, the optimum condition were (5 - 6), (25 - 30 ?C), 10 - 3 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29.5mv\decade), correlation coefficient r= 0.9990, detection limit (4.87x10 - 7 M ) and life time of the electrode was 26 days.The second part includes the use of Schiff's Base as ionophor in ISES MembranesThe second part includes construction of membrane selective electrodes for METO and METF drugs based on complexation of drugs Schiff METO and Schiff METF as Ionophor with Phospho Molybdic acid (PMA) as an active substance using Nitro benzene (NB) and Di - n - Butyl phthalate (DBPH) as a plasticizers , poly vinyl chloride was used as a matrix for all electrodes.The Characters of each electrode were as follow : 1.For the Metoclopramide - Phospho Molybdic acid (Schiff’s METO - PMA) electrode using (NB) as a plasticizers, the optimum condition were (4 - 6), (20 - 35 ?C), 10 - 4 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (19.90) mv/decade, correlation coefficient r= 0.9970, detection limit (4.5x10 - 7 M) and life time of the electrode was 122 days.2.For the Metoclopramide - Phospho Molybdic acid (Schiff’s METO - PMA) electrode using (DBPH) as a plasticizers, the optimum condition were (4 - 6), (20 - 35 ?C), 10 - 4 M for pH , temperature and concentration of filling solution respectively. The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29. 70) mv/decade, correlation coefficient r= 0.9950, detection limit (3.83x10 - 7 M )and life time of the electrode was 108 days.3.For the Metformin - Phospho Molybdic acid (Schiff’s METF - PMA) electrode using (NB) as a plasticizers, the optimum condition were (5 - 6), (25 - 35 ?C), 10 - 4 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29. 30) mv/decade, correlation coefficient r= 0.9970, detection limit (3.87x10 - 7M )and life time of the electrode was 102 days.4.For the Metformin - Phospho Molybdic acid (Schiff’s METF - PMA) electrode using (DBPH) as a plasticizers, the optimum condition were (5 - 6), (25 - 35 ?C), 10 - 4 M for pH , temperature and concentration of filling solution respectively.The linear concentration range was from (10 - 5 - 10 - 1) M with a slope of (29. 10) mv/decade, correlation coefficient r= 0.9980, detection limit (2.37x10 - 7 M )and life time of the electrode was 90 days
