- W2371122261 abstract "A method for the sequential determination of lead and zinc in copper concentrate by polarography is reported in this paper. Cupferron is used to eliminate the interference from Fe and Cu and cupferron also produces complex adsorption waves with Pb and Zn at -0.54 V and -0.99 V respectively. The detection limits are 40 μg/L and 80 μg/L with linear ranges of 80～1?600 μg/L and 120～1?200?μg/L for Pb and Zn respectively. The method has been applied to the determination of Pb and Zn in geological standard reference materials. The results are in agreement with reference values with precision of 6% RSD for Pb ( n =3) and 10% RSD ( n =3) for Zn." @default.
