| Abstract: | The effects of magnesium hydroxide dose, stirring time, temperature and pH value were investigated. The mechanism for the adsorption was studied. The results show that magnesium hydroxide has a better adsorption capacity, the removal rate reaches more than 99%. The adsorption isotherm accords with Langmuir mode, the maximum adsorption amount is 17.57 mg/g. When electroplate wastewater containing Cd 2+ ,Ni 2+ and Pb 2+ was absorbed by magnesium hydroxide, the contents of heavy metal ion are lower than the national discharge standard. |
