Derivative spectrophotometric determination of acetamiprid in the presence of 6-chloronicotinic acid

Abstract

A simple first-order derivative spectrophotometric method was developed for the simultaneous determination of acetamiprid and 6-chloronicotinic acid (6-CNA) at pH 7.0. By using the zero-crossing approach, acetamiprid was determined at 269.0 nm and 6-CNA at 216.0 nm with detection limits of 7.19×10-7 and 8.25×10-7 mol dm-3, respectively, and relative standard deviations not exceeding 1.2 % in the case of model systems.
