Adsorption of 2-Methylisoborneol in Drinking Water by Different Granular Carbons
Three kinds of granular carbon made from different materials of coal, coconut shell and jujube seed were evaluated for adsorption of 2-methylisoborneol in drinking water by equilibrium isotherm simulation. Results showed that Freundlich isotherm can more suitable to describe the adsorption of these three kinds of carbon. For coal-based, coconut shell and jujube seed carbon, the largest adsorption capacity of 2-MIB were 2225.0，3152.8 and 1E-07（ng/g）(L/ng)n respectively in pure water, and in raw water they were 559.6，612.5 and 6E-28（ng/g）(L/ng)n respectively, about one-fifth of those in pure water. Among the selected carbons, coconut shell carbon had the largest adsorption capacity, followed by coal-based and jujube seed carbon which can hardly absorb 2-MIB.
