A Simple Electrochemical Method for Nitrate Determination in Leafy Vegetables

Abstract

Nitrate could be determined by ion selective electrode (ISE) method for which one normally needs to create a calibration curve (semi-logarithmic) to find out the nitrate concentration in the unknown sample [15,16]. Since nitrate is an anion so it can be determined by the ion chromatographic method [17][18][19]. HPLC method is also a common method in
