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 the 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.
