摘要
建立紫外-可见分光光度法测定噻唑磷含量的方法。溶剂为正己烷,测定波长为213.9nm,样品质量浓度为36.375mg/L。采用对照比较法计算含量。噻唑磷在23.92~95.68mg/L质量浓度范围内呈线性关系线性相关系数为0.9996。精密度实验RSD不超过0.74%,准确性分析表明噻唑磷的回收率在100.21%~101.16%之间。
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%.
