| Abstract: | The new method of determining trace lead and cadmium in water by stripping voltammetry methods were introduced,which is rapid and simple,and the detection limits of lead and cadmium are 2.2×10~(-7)g/l and 5.6×10~(-7)g/l respectively.The recovery rates of the method are 98%-99% and 97%-98% respectively.It has been used to determine trace lead and cadmium in water with satisfactory results. |
