摘要：
Studies have been performed which demonstrate the influence of several anions on the removal of nickel cations from aqueous solutions by means of natural clinoptilolite. The experimental work performed showed that the ion exchange process is a fast process for both the ammonium and sodium converted clinoptilolite.The actual exchange capacity of sodium clinoptilolite was found lower compared to that of the ammonium clinoptilolite. Nickel removal was higher in the presence of nitrate anions followed by sulfate and chloride anions. For the Watt type electroplating solution the nickel was effectively removed by combining precipitation and ion exchange, the best results obtained with ammonium clinoptilolite.
