摘要：

Binding capacities and conditional stability constants for Cu and Cd in sewage sludges were determined. Two different sludges were investigated; a secondary sludge and an anaerobically digested sludge. Free metal 1on concentration were determined using differential pulse anodic stripping voltammetry (DPASV) and atomic absorption spectrometry following separation of bound and free species by dialysis. DPASV results are affected by complexes lability but the differences with dialysis measured values give information about metals availability. © 1990 Publications Division Selper Ltd.
