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.
