【摘要】：通过稀溶液法将聚合阳离子Zr~(4+)柱撑进入提纯钠基蒙脱石(Na-mt)层间合成锆柱撑蒙脱石(Zr-pmtn),再通过浸渍法制备活性炭负载锆柱撑蒙脱石(C/Zr-pmtn)。对C/Zr-pmtn进行的XRD分析表明:Zr-pmtn和活性炭以2∶1的质量比制备的C/Zr-pmtn具有较大的晶面间距。采用C/Zr-pmtn对丁基黄药进行吸附研究,结果表明:1向初始pH=3、浓度为20 mg/L的100 m L丁基黄药溶液中投加0.1 g的C/Zr-pmtn,20℃下吸附50 min,对丁基黄药的吸附量为19.38 mg/g,丁基黄药去除率达99.72%。2C/Zr-pmtn对丁基黄药的吸附符合二级动力学方程和Langmuir等温模型,C/Zr-pmtn对丁基黄药的最大吸附量达72.098 mg/g。可见,C/Zr-pmtn是选矿废水中丁基黄药的高效吸附剂。
[Abstract]:By dilute solution method of polymerization of cationic Zr~ (4+) into the purification of sodium montmorillonite pillared interlayer (Na-mt) synthesis zirconium pillared montmorillonite (Zr-pmtn), and then prepared by impregnation method of activated carbon supported zirconium pillared montmorillonite (C/Zr-pmtn). C/Zr-pmtn XRD analysis showed that Zr-pmtn and activated carbon with 2: 1 the mass ratio of C/Zr-pmtn prepared with larger spacing. Using C/Zr-pmtn of Butyl Xanthate by adsorption was studied, the results showed that: 1 to the initial pH=3 concentration of 20 mg/L and 100 m L added 0.1 g butyl xanthate solution C/Zr-pmtn, adsorption of 50 min at 20 DEG C, the adsorption amount of butyl xanthate was 19.38 mg/g, the removal rate of 99.72%.2C/Zr-pmtn butyl xanthate adsorption of butyl xanthate with two order kinetic equation and Langmuir isotherm model, the maximum adsorption capacity of C/Zr-pmtn butyl xanthate as 72.098 mg/g. visible, C/Zr-pmtn is high butyl xanthate in Flotation Wastewater Effective adsorbents.
