摘要
本文对粉煤灰酸浸法提铝后的硫酸铝溶液进行了有机络合法除铁研究,利用质量分数为30%的福美钠作为有机络合剂,确定了有机络合剂用量,温度以及反应时间与除铁效率的关系。实验表明:质量浓度30%福美钠用量为3mL,温度为30℃,反应时间为5min,除铁效果达到99.6%.
In this paper, iron ions removal from aluminum sulfate solution of fly ash treatment with organic complex- ion agent was studied, the mass fraction of 30% SDD uses as organic complexion agent. The experiments show that ： during 30% of the amount of sodium Fumei is 3mL,the temperature is 30℃, and reaction time is 5min. Iron remov- al is 99.6%.
