摘要
研究了NDA-66新型超高交联树脂对邻苯二甲酸的吸附及脱附性能。实验结果表明:静态吸附过程中,在初始邻苯二甲酸质量浓度1 000 mg/L、溶液pH=2.0、吸附时间600 min的条件下,吸附量可达190 mg/g;动态吸附过程中,处理11吸附床层体积倍数(BV)的邻苯二甲酸溶液,当溶液流量为1.5 BV/h时,吸附率可达100%;动态脱附过程中,在w(NaOH)=6%、脱附温度328 K的最佳脱附条件下,脱附率可达99%以上。
The adsorption and desorption of o-phthalic acid on hypercrosslinked resin NDA-66 were studied. The results show that：For static adsorption,under the conditions of initial mass concentration of o-phthalic acid 1 000 mg/L,solution pH 2.0 and adsorption time 600 min,the adsorption quantity can reach 190 mg/g;For dynamic adsorption,when the solution flow is 1.5 BV/h and o-phthalic acid volume is 11 BV,the adsorption rate can reach 100%;Under the optimum desorption conditions of w（NaOH） 6% and desorption temperature 328 K,the desorption rate can reach over 99%.
