Determination of Some Nutrients by Home-made Siemi-automated Ion Chromatography System

This work demonstrates the application of semi-automated home-made IC system for determination of NO2-, NO2- and PO43- ions with simple, eco and simultaneous method in water, soft drink and pharmaceutical preparations. 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 PO43- ions respectively.
