摘要
以Mn、Sn、S,K2CO3为原料,通过水热法在200℃下合成K2xMnxSn3-xS6,进行SEM,FTIR表征。该化合物有很好的层状结构,层间有结晶水。开展对Cu2+的吸附研究,结果表明KMSS对Cu2+在酸性、室温下具有良好的吸附能力,以化学吸附为主,符合Langmuir等温模型。在最佳条件下,最大吸附量为211.056 mg/g。
In the paper, using the hydrothermal method, K2xMnxSn3xS6（KMSS） was synthesized with S, Sn, Mn elemental, K2CO3 as raw material, when heated to 200 ℃, and was characterized by series of methods（SEM, XRD, FTIR）. SEM results show that the compound has good layer structure; FTIR showed that the compounds containing water of crystallization. The results show that the adsorption reaction of Cu2＋ on KMSS is good under the acidic and room temperature, the adsorption isotherm is conformity with the Langmuir isotherm adsorption model. Under best adsorption efficiency, the adsorption amount was 211.056 mg/g.
