摘要:
采取D201、D468、717、AB-8、D3520、D152、D155七种型号树脂,对含硫酸质量分数约为5%的工业废水中的铁离子(约1 000 mg/L)的吸附性能进行了筛选实验,并选择螯合树脂D468树脂研究其对含酸废水中铁离子的吸附特性,并考察了时间、温度及pH值对D468树脂吸附性能的影响.结果表明:室温下D468在30 min即可达到较大的吸附量2.33 mg/g;在25~55 ℃,温度对树脂吸附影响较小;pH值增大,吸附率上升.D468树脂在吸附后,废水中剩余铁离子约为251 000 mg/L,可回用于制备工业级硫酸.
Abstract:
The characteristics of seven resins D468, D201, 717, AB8, D3520, D152 and D155 for absorption of iron ions (about 1 000 mg/L) in industrial wastewater is studied.The D468 macroporous resin is selected studing its capacity of absorption for iron ions in industrial wastewater which contains 5% sulfuric acid. And the effect of absorption time, temperature and pH value on the absorption is also studied. The experimental results show that Chelating Resin D468 can achieve larger absorption quantity of 2.33 mg/g in 30 min at room temperature. At 25-55 ℃, the effect of temperature on the absorption capacity is little, and the absorption rate rise with pH value increasing. After D468 resin absorption, wastewater remains the iron ions about 25 mg/L, which can be reused for preparation of industrial grade sulfuric acid.
