Abstract


A novel nano-composite reagent (NCR) was prepared for the treatment of wastewaters containing copper chelates, such as CuEDTA, CuNTA, CuCA and CuDTPA etc. The experimental results showed that NCR could effectively remove chelated copper from wastewaters under conditions of pH 10 and NCR dosage 200 mg L-1, where the removal efficiency could reach as high as 98.94%. The turbidity of wastewater could be decreased to 1 NTU below after settling for 50 min, which indicated a good settling performance of the yielded precipitates.
