摘　　要：通过阳离子交换树脂对铬洗脱液脱除钠离子(简称"脱钠")的静态实验研究,筛选出脱钠树脂B,并对该树脂的再生工艺条件进行了优化。静态实验结果表明:当硫酸浓度为10%,再生9h,再生体积比(再生剂体积与树脂体积之比)为3:1,树脂再生度可达98%以上。Removal sodium from chromium eluent （short for ＂sodium-free＂） in static experimental study by cation exchange resin, select the sodium removal resin B, and make an optimization of regeneration process. The static experimental results show that when the concentration of sulfuric acid is 10%, regeneration 9 h, 3：1 as the regeneration of volume ratio between 10% sulphuric acid and resin, more than 98% of resin regeneration degree, can be reached.
