某水厂周边土壤中铬的测定

The Chrome in Soil Surrounding a Certain Water Plant

为了研究土壤中的铬是否会对某水厂源水构成威胁,文章对研究区内的土壤样品进行了分析测定。结果表明:水厂周边土壤各监测点位中的总铬含量均远低于土壤环境质量二级标准,且研究区内土壤对Cr^(6+)的吸附属于结合能较高的专性吸附,不易被解吸,对水厂源水的潜在威胁小。

In order to study whether the chromium in the soil poses a threat to the source water of a water plant,the soil samples in the study area are analyzed and determined.The results showed that the total chromium content in the monitoring sites of the surrounding soil was much lower than that of the soil environmental quality.The adsorption of Cr6+on the soil in the study area belongs to the specific adsorption of high binding energy,not easy to be desorbed,so the potential threat to water source water is small.
