中文摘要：
研究了竹炭对溶液中二价锰离子的吸附行为。试验结果表明：竹炭对锰2＋吸附的最佳酸度为pH=4.4;温度在298K时,竹炭对锰2＋的吸附平衡时间为6h,且竹炭粒径对吸附平衡时间基本不产生影响;锰2＋的初始浓度越大,一定量竹炭的吸附量越大;一定浓度、体积的溶液中,竹炭的投放量越大,去除率越大;在298～318K的温度范围内,吸附量呈现先增后减的趋势。
英文摘要：
The adsorption of divalent manganese ion by bamboo charcoal from the solution was studied. The results revealed that the optimal acidity for bamboo charcoal to adsorb Mg2＋ was 4.4,when the temperature was 298 K,the adsorption equilibrium time of bamboo charcoal for divalent manganese ion was 6 h,and the particle size of bamboo charcoal basically had no impact on the adsorption equilibrium time,the higher the initial concentration of divalent management ion,the more the adsorption volume of the bamboo charcoal with certain amount in the solution with certain concentration and volume,the more the bamboo charcoal,the higher the adsorption rate,and within the temperature range from 298 K to 318 K,the adsorption volume rose first and then declined.
