Determination of Nitrates in samples using Ion Selective Electrode with its new conditions

Abstract

New electric method depends on using new conditions for Nitrates selective electrode (PH=5.5, electrolyte Ammonium sulphate 3mol/l, Buffer Acetic acid -Sodium acetate, temperature 25 0 C) was applied for determination Nitrates concentration in different environmental samples (water-soil-vegetables). The study showed that this method has good sensitivity and it's accurate and reliable by finding SD, RSD, CL. By comparison between Nitrates concentration in studied samples, it was found that they are within permissible limits according to world health organization Reports.
