| 摘 要： | 通过对常压下采用工业稀盐酸和铝酸钙制备结晶氯化铝净水剂的试验研究,考察了铝酸钙低浓度盐酸浸取时原料配比、浸出时间、浸出温度对三氧化二铝溶出率的影响,并对三氯化铝结晶阶段的机理进行了探讨,实验结果表明低浓度工业废酸可以用于制备结晶氯化铝。项目研究成果为低浓度工业废盐酸的处置与利用提供了新的思路。

| Abstract: | Experimental study was conducted on the preparation of crystalline aluminum chloride from industrial diluted hydrochloric acid and calcium aluminates under atmospheric pressure condition.Influences of the dosage of hydrochloric acid,extracting time and extracting temperature on the extracting rate were examined,and the mechanism of aluminum chloride's crystallization was investigated as well.Experimental results showed that low-concentration industrial waste acid can be used for the preparation of crystalli... |
