土壤中Sb(Ⅲ)和Sb(Ⅴ)的有效提取与测定
Effective Extraction and Determination of Sb(Ⅲ)and Sb(Ⅴ)in Soil
摘要
Abstract
Among the various forms of antimony(Sb),Sb(Ⅲ)and Sb(Ⅴ)have higher toxicity and a higher proportion in the composition of antimony in urban soil.This research investigated the effects of factors including extraction instrument,extractants,extraction conditions,and chromatographic separation mobile phase conditions on the extraction and determination,and established a novel extraction-determination method for Sb(Ⅲ)and Sb(Ⅴ)in the soil.The highest extracting efficiency was obtained by soaking and oscillating soil samples in citric acid solution at 70℃first,then separated with dipotassium edetate and phthalic acid as mobile phase by liquid chromatography,and finally measured by inductively coupled plasma mass spectrometry.With the proposed method,low detection limits,good accuracies and precisions for both of Sb(Ⅲ)and Sb(Ⅴ)were obtained.It was highly recommended for the effective extraction and determination of antimony speciation in real soil samples.关键词
