腐植酸-N-异丙基丙烯酰胺交联树脂的合成及其对水相中锰(II)吸附性能的研究

The Synthesis of Humic Acid-N-Isopropyl Acrylamide Cross-Linked Resin and Its Adsorption of Mn(II) from Aqueous Solution

采用反相悬浮聚合法制备了腐植酸-N-异丙基丙烯酰胺交联树脂,通过静态吸附实验研究了其对水溶液中Mn(II)的吸附性能,探讨了吸附温度、pH值对水中Mn(II)吸附性能的影响。结果表明,腐植酸-N-异丙基丙烯酰胺交联树脂在pH值4~8范围内对Mn(II)具有良好的吸附能力,在32℃时对Mn(II)的平衡吸附量为1.2967 g/g,对Mn(II)吸附率达到99.5%以上。

A humic acid–N-isopropyl acrylamide cross-linked resin was synthesized by reversed-phase sus-pension polymerization .The cross-linked resin was used as an adsorbent in a series of bath ad-sorption experiments for the removal of Mn(II) from aqueous solution. The effects of adsorption temperature and pH value on adsorption property were discussed. The results showed that the equilibrium adsorption capacity and removal rate of Mn (II) were up to 1.2976 g/g and 99.5% re-spectively with pH 4 - 8 at 32?C.
