摘要:

Two techniques involving electrodeposition of Cu on a carbon rod (CR) prior to atomic absorption (AA) analysis are described. Thein situtechnique involves electrodeposition from ul samples contained in the well of the CR in an attempt to decrease matrix effects. The bulk electrolysis technique allows preconcentration of Cu on the CR from very dilute metal ion solutions. Analysis of Cu in solutions as dilute as 1.6 × 10−10M (70 ml volume) appears possible.
