Abstract

Abstract Simultaneous spectrophotometric determination of three neonicotinoid insecticides (acetamiprid,imidacloprid, and thiamethoxam) by a novel methodnamed generalized net analyte signal standard addition method (GNASSAM) in some binary and ternarysynthetic mixtures was investigated. For this purpose, standard addition was performed using a single standard solution consisting of a mixture ofstandards of all analytes. Savings in time and amount of used materials are some of the advantages of this method. All determinations showed appropriate applicability of this method with less than 5% error. This method may be applied for linearlydependent data in the presence of known interferents. The GNASSAM combines the advantages of both the generalized standard addition method and net analyte signal; therefore, it may be a properalternative for some other multivariate methods.
