| 摘 要： | 对过饱和铝酸钠溶液种分过程进行了实验研究。研究以不同添加剂对铝酸钠溶液分解率的影响规律。结果表明:在相同实验条件下,阴离子表面活性剂A、B可使分解率提高3%左右;非离子表面活性剂C、D可使分解率提高2%～8%左右。当阴离子表面活性剂E添加量为140mg/L时,分解率可提高5%左右;当非离子表面活性剂F添加量为3.57mg/L时,分解率提高18%左右。

Study of seeded precipitation of supersaturated sodium aluminate solution |

| Abstract: | The influence of the kind of surfactants and its amount on the process of seeded precipitation of supersaturated sodium aluminate solution was investigated in this paper.Results show that compared with the samples with no additive,anion surfactants A and B can increase the precipitation rate by 3%,non-ionic surfactants can increase the precipitation rate by 2%～8%.The precipitation rate increased by 5%,when the concentration of E was 140mg/L.The precipitation increased by 18% after adding 3.57mg/L non-ionic surfactant F. |
