摘　　要：研究了土壤中Ｃｒ６＋的提取测定方法．结果表明，用０．４ｍｏｌ／ＬＫＣｌ为提取剂，离心分离提取液，可简单、快速、准确地测定土壤中Ｃｒ６＋，所建立的方法适用于北方偏碱性土壤。A method for extracting hexavalent chromium in soil by means of different extraction reagent was studied.Based on this, a rapid,simple and accurate method for the determination of hexavalent chromium in alkalescent soil has been developed. The soil samples were extracted with 0.4 mol/L KCl. The extraction solution was separeted with centrifuge and determined by spectrophotometry.This method has been applied to contamination soil with satisfactory results.
