本文研究了由化学互贯及物理互贯法制得的大孔交联聚苯乙烯(PS)/聚氯乙烯(PVC)互贯弱碱树脂(分别称为DXP型和DXF型)对苯酚等有机质的吸着作用。结果表明,DXF吸酚受PH的影响行为与一般的弱碱树脂相似,而DXP的吸酚容量与PH的关系曲线呈S形。DXP特殊的吸酚行为归因于这种树脂两网互贯程度较大以致吸酚时有显著的协同效应,这种效应在不同的PH范围既可促进、也可减弱树脂对酚的吸着作用。DXF由于两网互贯作用小,协同效应不显著。协同效应也反映在DXP用于按蜜脱色及有机废水脱COD时有较好的效果。
In this paper, macroporous cross-linked polystyrene (PS) / polyvinyl chloride (PVC) interpenetrating weak base resins (DXP and DXF respectively) The sorption. The results showed that the DXF phenol absorption by the PH effect similar to the general weak base resin, and DXP phenol absorption capacity and PH curve was S-shaped. DXP special phenol-induced behavior attributed to the greater degree of mutual interaction between the two resin net so that there is a significant synergistic effect when phenol absorption, this effect can be promoted in different PH range, but also weakened the resin sorption of phenol . DXF interoperability between the two networks is small, synergy is not significant. The synergistic effect is also reflected in the DXP for the honey decolorization and COD removal of organic wastewater has a better effect.
