| Abstract: | Taking lead and cadmium as examples,the MetalSafe portable analyzer was used to fast detect heavy metals in water.The principle of anodic stripping voltammetry,operating steps and technological parameters were described.The results of standard addition method showed good linearity was obtained in calibration curves of lead and cadmium,the detection limits 0.022 μg/L and 0.025 μg/L separately,RSDs of two concentration levels of lead and cadmium ≤0.6%,relative errors 5%.Compared with lead testing result of AAS,the data showed no significance difference by homogeneity test of variances and student test. |
