多泥沙水体中六六六(HCH)残留SPE提取方法的优化

Optimization of Extraction Method for HCH in the Sediment-Laden Water

多泥沙河流中六六六(HCH)的提取一直是分析化学领域的难点之一。选定固相萃取法(SPE)作为样品的提取方法,并以α-HCH、β-HCH、γ-HCH、δ-HCH为标准溶液,对提取方法进行了优化,确定了适应于多泥沙水体中六六六农药残留的SPE提取流程。该流程适用于地表水和地下水、工业废水等含泥沙或不含泥沙的水体中六六六农药残留的提取,且有很强的适应性和可重复性。

Extracting HCH from the sediment-laden river is one of difficult problems in the field of analytical chemistry.This research selected Solid Phase Extraction as the extraction method,selected α-HCH、β-HCH、γ-HCH、δ-HCH as the standard solution,and optimized the extraction method.Lastly,we established the circuit of extracting HCH from the sediment-laden river.This circuit adjust to extract HCH from surface water,groundwater,industrial wastewater and others which contain sand or not.This circuit have strong adaptability and repeatability.
