摘要: 研究了腐殖酸分子量对弱碱性大孔树脂吸附腐殖酸的影响, 阐明了溶液中小分子芳环化合物(苯酚)及盐含量对树脂吸附腐殖酸的影响机制. 结果表明, 树脂对低分子量腐殖酸的吸附效果要优于高分子量腐殖酸; 低浓度苯酚在溶液中可以促进树脂吸附腐殖酸, 但溶液中苯酚浓度过高会对树脂吸附腐殖酸产生抑制作用; 溶液中的盐对树脂吸附腐殖酸的影响取决于溶液的pH值.

关键词: 弱碱性树脂, 腐殖酸, 吸附

Abstract: Adsorptions of humic acid(HA) and tanic acid(TA) on weakly basic resin(D-301) were investigated. The result indicates high molecular weight of humic acid can decrease resins adsorption capacity. Furthermore, resins adsorption capacity for humic acid is slightly higher in the presence of low concentration of phenol, but a decrease in resins adsorption capacity for humic acid is observed in the test when concentration of phenol is high. NaCl and pH also show an influence to resin's adsorption capacity.

Key words: Weakly basic resin, Humic acid, Adsorption
