AI Technical Summary
Existing powdered activated carbon has limited adsorption efficiency and capacity when removing odor-causing substances such as 2-methylisoborneol (2-MIB) and geosmin (GSM) from water, resulting in high operating costs and potentially affecting the quality of the effluent.
Commercially available powdered carbon was modified using manganese nitrate and potassium hydroxide solutions. Through impregnation, drying, heat treatment, and sieving, a microporous powdered carbon material was prepared, which reduced oxygen-containing functional groups and increased specific surface area and hydrophobicity.
It significantly improved the adsorption efficiency and capacity of powdered carbon materials for 2-MIB and GSM, enhanced the effectiveness of emergency treatment, and improved the stability and selectivity of the materials.
