摘要
利用生物质香蕉皮和生物炭香蕉皮作为吸附剂,探究吸附剂性质、吸附剂量、pH、铬溶液初始浓度、震荡时间对香蕉皮吸附Cr^(6+)效果的影响。结果表明:生物质香蕉皮的吸附效果高于生物炭香蕉皮的吸附效果,最佳吸附条件为:不做任何改性处理、吸附剂量0.2 g、模拟废液pH为2、Cr^(6+)初始浓度为12.5 mg/mL、震荡时间45 min,在此条件下香蕉皮对Cr^(6+)的去除率为98.77%、单位吸附量为6.17 mg/g,经吸附处理后的溶液含Cr 6+浓度为0.15 mg/mL。
Using biomass banana peel and biochar banana peel as adsorptivet,the effect of adsorbent properties,adsorbent quantity,initial concentration and shock time on the hexavalent chromium adsorption effect was explored.The results showed that the adsorption effect of biomass banana skin was higher than that of biocharcoal banana skin.The optimal adsorption conditions were as follows:no modification treatment,adsorbent amount was 0.2 g,pH of chromium wastewater simulation solution was 2,Cr^(6+)initial concentration was 12.5 mg/mL,shock time was 45 min.Under these conditions,the removal rate of Cr^(6+)by banana peel was 98.77%and the unit adsorption amount was 6.17 mg/g,The adsorbed solution contained a Cr 6^(+)concentration of 0.15 mg/mL.
