| Abstract: | A method for determining the content of fosthiazate was established with UV-VIS spectrophotometry,n-hexane as solvent,and the absorptive wavelength was 213.9 nm.The determination of content was 36.375 mg/L.The calibration curve of fosthiazate was linear over the range of 23.92-95.68 mg/L.The linear correlation was 0.9996.The relative standard deviations was not more than 0.74%and the recoveries were from 100.21-101.16%. |
