摘    要:通过研究DY-001,XB-001,NDA-4043种树脂对1,4-二羟基蒽醌废水中邻苯二甲酸的吸附效果,确定了1,4-二羟基蒽醌废水中邻苯二甲酸的回收的最佳工艺条件;选用吸附树脂NDA-404作为废水处理使用,在常温下控制废水的流速为2BV/h,吸附效果到达93%以上;采用酸性乙醇洗脱液(乙醇与1mol/L的盐酸按体积比为2:1)洗脱,在微热的条件下控制流速为1.5BV/h,脱附效果可以达到91.21%;将洗脱液浓缩可得纯度较高的邻苯二甲酸晶体。

关 键 词:树脂  吸附  脱附  1,4-二羟基蒽醌废水  邻苯二甲酸

Abstract:Study of adsorption effect of o--Phthalic Acid by DY--001, XB--001 and NDA--404 macroreticular resin showed the best treatment. NDA--404 was used for wastewater treatment, at room temperature control, wastewater flow rate 2BV/h, the adsorption rate was above 93%. Used the mixture of cobol and 1 mol/L hydrochloric acid (mixed with the ratio of 2 : 1) as desorption solution, the micro--heat conditions to 1.5BV/h speed of desorption, desorption effects can reach 86%. By heating evaporation, the high purity phthalic acid crystals will be cooled and filtered.
Keywords:resin  adsorption  adsorbent  1  4--dihydroxy anthraquinone wastewater  o--Phthalic Acid
