Study on the treatment of chromium-containing wastewater by sulphonated peat coal;
磺化泥炭吸附处理含铬废水的研究
The thermodynamics characteristics of the adsorption of Cr(Ⅵ)by sulphonated peat coal in aqueous solution were investigated under static conditions,and the adsorption isotherms at different temperatures were measured.
在静态条件下,研究了水溶液中磺化泥炭吸附铬(Ⅵ)的热力学特性,测定了不同温度下磺化泥炭吸附铬(Ⅵ)的吸附等温线。
The results showed that nitrifying peat and sulphonated peat have a good absorption effect on Pb 2+ and Cu 2+ ,and the effect of sulphonated peat was better.
结果表明 ,硝化泥炭、磺化泥碳对Pb2 + 、Cu2 + 重金属离子有很好的吸附性 ,以磺化泥炭吸附效果较好 ,其吸附规律基本符合Langmuir方
