摘要: The precipitation of barium, zinc, lead, copper and silver chromates was studied in the presence chelating organic anions gluconate, tartrate, citrate, aspartate, glutamate E.D.T. Aate. Generally, these chelators complex metal cation reduce free mean chromate concentrations solution. rates nucleation with microcrystallite formation were then markedly reduced induction periods increased from below 1 sec to well above 100,000 increasing chelator/cation concentration ratio; experimental results expressed by relations; The coefficients F at any related turn stability constants metal-chelator complexes.
