钠基蒙脱石对水溶液中Cu2+的吸附作用研究
Study on the Adsorption of Na-Montmorillonite to Cu2+ from Aqueous Solution
【摘要】 研究了钠基蒙脱石对水溶液中Cu2+的吸附性能。考察了各种反应条件,如离子浓度、反应时间、磁场强度以及pH值对钠基蒙脱石吸附Cu2+量的影响。结果表明:水溶液中Cu2+初始浓度以0.1mol/L以下为宜,pH值应控制在3~5范围内,较佳的反应时间为50min;在磁场中磁场强度提高能促进钠基蒙脱石对水溶液中Cu2+的吸附。
【Abstract】 In this paper, the adsorption properties of Na-montmorillonites to Cu2+ were studied. The effects of reaction conditions on Cu2+ adsorption content such as concentration, time, pH value, were researched. The results showed that concentration of Cu2+ 0.1mol/L, reaction time 50 min, pH value 3~5; the adsorption content of Na-montmorillonites to Cu2+ increased with magnetic density rising.
