The Research for Microwave Modified Vermiculite Adsorption of Zn²⁺

Abstract:

The impact on the adsorption of Zn²⁺of these factors, initial concentration, modification time, reaction time vermiculite dosage, reaction temperature and pH having, and absorption mechanism are studied . The results show that: microwave modification time 30s, reaction time 40min, modified vermiculite dosage 8g/L, reaction temperature 30°C, reaction pH 6, Zn²⁺ adsorption rate can reach 97.91%, adsorption isotherms of Zn²⁺ by microwave modified vermiculite show that the adsorption equilibrium is consistent with Langmuir curves, correlation coefficient reached to 0.997 at room temperature.
