摘要:
铬是一种大量富集于水环境中的污染物,会严重威胁和损害人的健康。文章以柠檬酸改性的花生壳为吸附剂,考察了吸附剂投加量、吸附时间、溶液初始pH 值、温度及溶液初始浓度等因素对Cr(VI)吸附性能的影响,并通过正交实验,优化吸附条件。结果表明,在初始浓度为10mg/L,吸附时间90min,pH 值为2,吸附温度为35℃的条件下,此时去除率可达到83.78%。
Abstract:
Chromium is a kind of pollutant in water environment, which can seriously threaten and harm human health. In this paper, the adsorption property of peanut shell modified by citric acid for the removal of Cr(VI) from aqueous solution was studied. The effect of the factors on the adsorption were investigated including adsorbent dosage, absorption time, the solution pH value, temperature and initial concentration of solution. Based on these, the adsorption conditions were optimized by orthogonal experiment. The results showed that the Cr(VI) removal efficiency achieved 83.78% when the initial concentration of Cr(VI) is 10mg/L, pH value is 2, adsorption time is 90min, and temperature is 35℃.
