无公害蔬菜、灌溉水、种植土壤中Pb、As、Cd、Cr的测定
Determination of Pb,As,Cd,Cr in Nonpolluted Vegetables,Irrigated Water and Planting Soil
【摘要】 采用原子吸收光谱法测定了广西区内几个无公害生产基地土壤、蔬菜、水样中Pb、As、Cd、Cr的含量 ,RSD <7% ,回收率在 94 %~ 110 %之间。用本法测定GBW 0 830 2土壤标准物质 ,测得值与推荐值基本一致。
【Abstract】 The content of Pb,As,Cd,Cr of planting soil,vegetables and irrigated water in several producing base which has no environmental pollution was analyzed by AAS The RSD and recovery of this method is less than 7% and from 94% to 110% respectively The determined results of GBW 08302 soil standard substance are consistent with that of recommendation
