摘要：

Humic acids were extracted from lake sediment using a variety of solvents. The humic acids were purified by dialysis. The humic acid complexation capacity for copper and cadmium was determined polarographically. The complexation capacity was found to be a function of the extraction solvent. Complexation capacity was also found to be a function of the salinity of the solution with capacity decreasing as salinity increased.
