摘要
针对煤泥水中金属离子含量变化,从反应时间、pH值和反应温度三方面研究了钙、镁离子对高岭石、蒙脱石、煤的吸附特性。试验结果表明:钙、镁离子对高岭石、蒙脱石、煤具有相似的吸附特点,但钙离子比镁离子吸附能力强,煤泥水的pH值决定钙、镁离子的存在状态。
The article was aimed at the changes of metal ion content in water of the slime.Based on the reaction time,pH value and temperature,the adsorption characteristics of Mg2＋ and Ca2＋ to kaolinite,montmorillonite and coal have been studied.The results showed that Mg2＋ and Ca2＋ had the similar adsorption characteristics to kaolinite,montmorillonite and coal.But the absorption ability of Ca2＋ was better than Mg2＋.The pH value of slurry determined the presence of calcium and magnesium status.
