RESEARCH SEPARATE OF SOME HEAVY METAL IONS FROM PLATING METAL WASTEWATER BY FERROMAGNETISM NANO-OXIDE AND FERROMAGNETISM NANO-OH MATERIALS

Tóm tắt

The study evaluated the effect of artificial plating wastewater treatment with the survey parameters: when using ferromagnetic nano (CoFe₂O₄) and ferromagnetic Nano-OH material, pH = 5; Ni²⁺ = 25 (mg/l), Cu²⁺ = 25 (mg/), Zn²⁺ = 25 (mg/l). Results of the study on the plating wastewater, the efficiency of removing ion Ni²⁺, Cu²⁺, Zn²⁺ when using ferromagnetism nano materials, the results  are as follows: Ni²⁺ reached 62.53%; Cu²⁺ reached 69.32% and Zn²⁺ reached 61.47%. While, using ferromagnetism nano -OH materials, the results are as follows: Ni²⁺ reached 65.45%; Cu²⁺ reached 67.85% and Zn²⁺ reached 84.20%. In sum, the results of the study indicated the potential of new materials for improving and treating wastewater.
