Study on Adsorption Performance for Cu^2+and Cd^2+of the Leaching Residue of Spent Automobile Exhaust Gas Purifier Catalysts AITranslate
Abstract AITranslate
Using the leaching residue from acid treatment of spent automobile exhaust gas purifier catalysts as the adsorbent,the heavy metals Cu^2+and Cd^2+in the wastewater simulation solution were separated,and the effects of temperature,pH,adsorbent amount and adsorption time on the adsorption rates of Cu^2+and Cd^2+were investigated.The optimal adsorption conditions were obtained:temperature of 50℃,pH of 5.5,adsorbent amount of 0.5g and adsorption time of 1h.Under the optimal conditions,the adsorption rates of Cu^2+and Cd^2+in 20mg/L solution are 99.95%and 99.22%,and the saturated adsorption capacities of Cu^2+and Cd^2+in 1g/L solution are 99.61mg/g and 42.17mg/g,respectively.The adsorption of Cu^2+and Cd^2+by the leaching residue conforms to the second-order kinetic model,and chemical adsorption is the dominant adsorption mode.
