FAAS法测定土壤和蔬菜中的Cd元素
Measurement of Cadmium Content in Soils and Vegetables by FAAS
【摘要】 本文以油菜为试材,用FAAS法对受Cd污染土壤中的全量Cd、有效态Cd以及油菜茎叶中的Cd含量进行了测定与分析。同时对土壤全量Cd、有效态Cd及茎叶中Cd的样品予处理方法进行了比较研究。结果表明,方法回收率在96%以上,样品测定的相对标准偏差小于3.97%。本方法快速、准确、干扰少。测定结果满意
【Abstract】 The analytical and testing centre the total cadmium(Cd) and the available Cd contents in different Cd polluted soils were measured by FAAS.The Cd content in the stems and leaves of cole was tested in the same way.The methods of sample pretreatment for the total Cd and available Cd in soils and in cole were compared respectively.The standard sample recovery rates were all above 96 percent,and the relative standard deviations were less than 3 97 percent.The FAAS is rapid and accurate.
