| Abstract: | The application in the detemination of lead in wine by carbon fiber electrode and capability testing were studied.The determination of lead in solution of 10.0 mg/L ratio was 93.5%,RSD was( n =11)<8.3%.Carbon fiber electrode's peak high was 268.57 μA/V,standard deviation was 3.256 μA/V,RSD was 1.213%.The GC electrode's peak high electrode have a higher stability than GC electrode. |
