Determination of High-Saline Cadmium in the Soil by GFAAS

XUE Qiu-Wang CHEN Fu-Qiang (Guangdong Material Testing Center,No.751 Dongfengdonglu,Guangzhou 510080,P,R.China)  
The high-saline cadmium in the soil was determined by GFAAS under the suitable conditions.It was found that high-saline situation will lead to serious interference,and difficult to achieve satisfactory results,which was eliminated by atomization at lower temperature to improve the sensitivity as well as the precision and convenience and protect the graphite tube to reduce the production cost.The detection limit is 0.003μg/L and the relative standard deviation(n=12) is 5.28%.
