摘　　要：研究了废弃泥浆中的Cr（Ⅵ）提取测定方法并与土壤的浸提方法进行比较.结果表明,用0.1mol/L的KH2PO4为提取剂高速搅拌离心,分离提取液,可简单、快速、准确地测定废弃泥浆中的Cr（Ⅵ）.该方法的相对标准偏差为0.6%～2.5%,加标回收率86%～98%.The extraction method of hexavlent chromium from waste drilling mud was studied , and compared to lixiviation method of soil. The results showed that abstraction by 0. 1mol/L KH2PO4 was isolated extracts after high speed and stirring centrifuges. The method is proved to be simple and fast and accurate to determination of hexavlent chromium. The RSD% Of standards was 0.6% - 2.5% , the recovery rate of the standards was between 86 % - 98 % .
