Extraction of acephate pesticide in environmental and agricultural samples by spectrophotometric method

Abstract

In the present study, we have synthesis the azo dye for the reaction of p-amino antipyrine with HCl in NaNO2 solution a 1:1 ​M ratio that was kept -5°C for 1–2 ​h, as result the absorption spectra observed at λmax ​= ​460 ​nm. Beer’s law is obeyed over the awareness variety of 1 ​μg–100 ​μg ​mL-1. The standard deviation and relative well-known deviation are 0.007 and 1.38%. The molar absorptivity and Sandell's sensitivity had been located to be 0.98 ​× ​105 ​L ​mol-1 ​cm-1 and 0.99 ​× ​10-3 ​μg ​cm-2, respectively. Spectroscopy method used for the detection of Acephate pesticides on vegetable, fruit, soil, and water samples. FTIR method was used to consider and achieve structural information about the presented intermolecular interactions for vegetable samples. The eco-friendliness of the developed methods was assessed using the spectroscopy analytical tool on vegetables, fruit, soil, and water samples.
