摘要
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 7.19x10(-7) and 8.25x10(-7) mol dm(-3), respectively, and relative standard deviations not exceeding 1.2 % in the case of model systems.
