المستخلص: This work includes three chapters. The first chapter focuses in general on chromatography and specifically on Ion Chromatography ( IC ) and recent application for some nutrient determination .The second chapter, Experimental parts, describes all parts of the homemade semi - automated IC system, procedure solution chemicals sampling and the optimu m conditions used in this study also illustrate.The last chapter , result and dissection demonstrates the application of IC system for determination of NO2 - NO2 - and PO4 3 - ions in details.Linearity's were in the range 2.5 - 12.5 , 2.5 - 12.5 and 7.0 - 35 mg/L with regression coefficient 0.9950 , 0.9960 and 0.9990 the ± RSD % equal to ± 0.45% , ± 0.56% and ± 0.51 % the recoveries were the range 100% , 96% and 95% which were found by standard additions method the sample throughput were 8.0, 6.0 and 3.0 sample/hour for NO2 - ,NO2 - and PO4 3 - ions respectively .The final parts in this chapter displays the application of the IC systemfor determination of NO2 - ,NO2 - and PO43 - ions in water some pharmaceutical preparations and soft drinks samples with simple eco and simultaneous method .
