Study on adsorption of coal ash coagulant on Cu²⁺ in waste leachate

Coal ash and waste aluminum were used to produce coal ash coagulant under a certain condition.The experiment result showed that coal ash coagulant can remove Cu²⁺ in waste leachate effectively. Under the best condition,the removal rate of coal ash coagulant on Cu²⁺ in waste leachate was 72.1%.It was 134.1% higher than the common coal ash.
