Abstract |
Concentrations of magnesium found in sea water are capable of precipitating cadmium humate from water solution. Speciation calculations and kinetic considerations indicate that dissociation of the cadmium complexes occurs during the precipitation process. For a sequence of divalent metal cations, lead is the most effective precipitator of humic acid, whereas magnesium is least effective. The order is lead > copper > cadmium > barium > zinc > nickel > calcium > strontium > magnesium. |
