The determination of cadmium in electricity plastics by carbon fiber electrode Stripping voltammetry

The application in the determination of cadmium in electricity plastic by carbon fiber electrode and capability testing were studied.The determination of cadmium in solution of 10.0 mg/L Hg2+-0.25mol/L hydrochloric acid with a test limit of 0.080μg/L.The standard add recovery ratio was 92.6%,RSD was(n=11)7.5%.carbon fiber electrode’s peak high was 276.51μA/V,Standard deviation was 3.112μA/V,RSD was1.116%.The GC electrode’ s peak high was 365.4μA/V,Standard deviation was 5.246μA/V,RSD was1.512%.The carbon fiber electrode have a higher stability than GC electrode.
