RESEARCH SEPARATE OF SOME HEAVY METAL IONS FROM PLATING METAL WASTEWATER BY FERROMAGNETISM NANO-OXIDE AND FERROMAGNETISM NANO-OH MATERIALS /TRINH DIEP PHUONG DANH...[VÀ NHỮNG NGƯỜI KHÁC], TẠP CHÍ ĐẠI HỌC THỦ DẦU MỘT, SỐ 1(40),2019,TR.11-17

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 resultsare as follows:Ni2+reached 62.53%; Cu2+reached 69.32% and Zn2+reached 61.47%. While, using ferromagnetism nano -OH materials, the results areasfollows: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
