| 摘 要： | 利用TiO2掺杂Pd2+吸附剂进行了酸性As(Ⅲ)废水的去除实验,并与活性炭吸附法进行了对比,考察了吸附时间、吸附剂用量、溶液pH值等因素对实验的影响.结果表明,对于ρ(As(Ⅲ))=15mg/L的水样,As(Ⅲ)的去除率达98.5%,高于或相当于活性炭吸附法,处理后的水质达到了国家排放标准. |

| Abstract: | The established method which uses a titania intermingle adsorbent to remove the As(Ⅲ) in waste water was compared with the method using the active carbon adsorbent.The study was focused on the effect of adsorbing time,the quantity of the adsorbent and the pH of the fluids. The results show that if the content of the As(Ⅲ) in waste water is 15 mg/L with the titania as adsorbent, the removal rate of As(Ⅲ) will reach (98.5%,) which is equal to or obviously higher than using active carbon adsorbent. The effluent quality meets (National) Discharge Standard. The adsorbing mechanism was also studied preliminarily. |
