Chemical Precipitation - an overview | ScienceDirect Topics
Chemical precipitation or reagent coagulation precipitates impurities from purified water via change of pH, electrooxidising potential or coprecipitation using precipitating agents (coagulants) such as ferrous or aluminium sulphates (IAEA, 1992).Reagent oxidation is a special case of reagent coagulation in which oxidising reagents (e.g., potassium permanganate or .Get Price
