【摘要】 比较了 D2 90、D2 96、D30 1、D370、D372、D380 6种树脂对 β盐母液中 1-萘磺酸钠的静态交换性能 ,筛选出 D2 96用以回收 β盐母液中的 1-萘磺酸钠 ;进行了 p H、接触时间、交换温度等影响因素的条件试验及树脂再生试验 ,得到 1-萘磺酸钠收率 80 %以上。更多还原

【Abstract】 Based on comparison of static exchange performance of six resins (D290,D296,D301,D370,D372,D380)on sodium 1 naphthalenesulphonate,the resin D380 was selected to recover sodium 1 naphthalenesulphonate from β salt mother liquor.The effecting factors such as pH, contact time,exchange temperature and so on were investigated and resin regeneration was carried out.The recovery rate of sodium 1 naphthalenesulphonate was over 80%.更多还原
