层迭灵芝子实体及其制备炭吸附Cd2+的研究
Sorption of Cadmium Ion on Sporophore and Biochar of Ganoderma lobatum
摘要
Abstract
Sorption capacities of Cd2+from aqueous solutions on the sporophore and biochar of Ganoderma lobatum were evaluated under different conditions including adsorbent doses, pH value of solution, contact time and initial Cd2+concentrations. The results showed that, when the mass concentration of Cd2+was 10 mg/L, the removal efficiencies of Cd2+for sporophore and biochar were 94.50 % and 92.75 %,respectively,under optimum conditions of adsorbent dose of 0.2 g, pH value 7 and contact time 480 min. The sorption rate of Cd2+on sporophor was significantly higher than that on biochar,but no significant difference for sorption capacity could be observed between sporophore and biochar. Langmuir and Freundlich models could be used to describe the adsorption data,the results showed that the adsorption process of Cd2+on sporophore was consistent with the Freundlich model, while the adsorption process on the biochar was more consistent with the Langmuir model. The sorption processes of sporophore and biochar for Cd2+followed well with pseudo second order kinetics.关键词
