Abstract: In order to address the low utilization rate and severe storage pollution of electrolytic manganese residue (EMR),this study developed porous ceramic materials using non-desulfurized EMR,waste glass,and kaolin as raw materials through a pore-forming additive addition, press forming, pressureless sintering process. Through orthogonal experiments to optimize the raw material ratios and process parameters,it was determined that when the addition of fly ash was 15%,the mass ratio of raw materials (manganese slag,waste glass and kaolin) was 3 ∶6 ∶1,the molding pressure was 10 MPa,and the sintering temperature was 975 ℃ ,the resulting material had the best overall performance,with a compressive strength of 214 MPa,bulk density of 1. 83 g / cm 3 ,and the adsorption capacity of Pb 2+ of 7. 79 mg / g. Further adsorption experiments showed that the adsorption and removal of Pb 2+ by the porous ceramics reached 7. 86 mg / g and 87. 69%,respectively,when the reaction was carried out for 540 min at pH= 1. 5,initial concentration of 100 mg / L of Pb 2+ ,temperature of 25 ℃ ,and oscillation rate of 170 r/ min. This study provides a new idea for the resource utilization of electrolytic manganese slag,and effectively achieves the dual goals of solid waste co-disposal and heavy metal pollution control.
