Experimental Study on the Modification of Granular Activated Carbon by Potassium Permanganate to Adsorb Cu²⁺ in the Water

Abstract:

This document studies test methods on modification of activated carbon by potassium permanganate to adsorb Cu²⁺. Ensure all factors’ effects on Cu²⁺ removal. Use potassium permanganate solution to modify activated carbon, investigate main factors’ effects on Cu²⁺ removal and analyze mechanism by changing potassium permanganate solution concentration, adsorption time, activated carbon’s additive amount and temperature. The results show that modification of activated carbon by 0.03mol/L potassium permanganate solution (0.03K-GAC) can adsorb Cu²⁺ best. 0.03K-GAC’s removal rate on Cu²⁺ is 98% when the initial concentration of Cu²⁺ is 50mg/L, the additive amount of 0.03K-GAC is 2.0g, the pH value is 5.5, the temperature is 25°C and the adsorption time is 4h. Modification of activated carbon by potassium permanganate has good adsorbability on Cu²⁺. Potassium permanganate solution concentration, adsorption time and additive amount can influence the adsorption of Cu²⁺ by activated carbon. However, temperature’s influence on the effect of adsorption is non-significant.
