大孔吸附树脂脱除天然碱中有机质的实验

Experimental investigation on the removal of organic matter in trona using macroporous adsorption resins

研究了弱极性或非极性大孔吸附树脂脱除天然碱中可溶有机质的方法。结果表明,D4020型大孔吸附树脂对天然碱碱液有机质的脱除率可达50%以上,优于活性炭;吸附有机质后的D4020型树脂可用氢氧化钠与丙酮联合处理再生,再生树脂平均吸附容量可恢复至80%以上。

An experiment investigation on the removal of the soluble organic matters in trona using macro- porous resins was conducted. The results demonstrated that the adsorption property of the D4020 style maeroporous resin was better than that of the active carbon at the same conditions and the removal ratio of soluble organic matters was higher than 50%. Compared with that of fresh the resin, the mean adsorption capacity of the resin regenerated by sodium hydroxide and acetone, the average adsorption capacity may up to 80%.
