A guide to the economic removal of metals from aqueous solutions

Water pollution is topic of immense and common concern throughout the world. This book presents the results and data from research and adsorption experiments carried out on the removal of nickel and chromium (as well as other metals)from aqueous solutions using modified silica sand.
