Study on Lead Adsorption Properties of Metakaolin/Red Mud Geopolymer

Abstract:

Red mud may cause serious pollution to soil, water, and air. Lead can seriously harm biological and even human health. This chapter summarizes the adsorption properties of metakaolin/red mud base polymer for Pb (Ⅱ). Under optimized conditions, with 0.6g/L adsorbent, pH value of 5, and adsorption time of 120 minutes, the adsorption capacity reached 122.58mg/g, and the removal rate was 73.55%. This will help to mitigate the threat of red mud and lead wastewater to human health and the environment, providing an important reference for water pollution control.
