| Abstract: | Abstract A method for the indirect determination of the pesticide malathion by atomic absorption spectrophotometry (AAS) is proposed and compared with the standard spectrophotometric method. A study of the influence of the different variables on the hydrolysis and extraction is carried out in order to obtain the best experimental conditions. The proposed method offers clear advantages over the standard procedure because of the instability of the Cu (II) complex formed. Both methods are applied to the determination of malathion in two commercial formulations. |
