摘要
采用聚硅酸对活性氧化铝进行改性,研究了SiO2百分含量、聚硅酸浸泡时间、焙烧温度及焙烧时间对改性活性氧化铝除氟性能的影响。结果表明,改性活性氧化铝能将水中的氟离子浓度从9.5 mg/L降低到0.89 mg/L,吸附容量提高了30%。因此,聚硅酸改性能有效提高活性氧化铝的除氟性能。
Using polysilicate on modification of activated had been discussed, such as the content of SiO2, soaking alumina. The influence factors of modification time, calcination temperature and calcination time, etc. The results show that the fluorinion concentration could be decreased from 9.5 mg/L to 0.89 mg/L by activated alumina modified with polysilicate in water, and the adsorption capacity increased by 30%. Therefore, modification with polysilicate could effectively improve the performance of activated alumina fluoride.
