摘　　要：有机染料在生活和工业生产中被广泛使用,由于染料的过度使用而带来的污染日益严重,对人类的健康产生重大威胁.笔者通过一步水热法合成由多个纳米片组成的束状Co_(0.85)Se/Cu(OH)_(2)纳米复合物.室温下该复合物对废水中的刚果红(CR)具有较高的吸附能力,对CR最大吸附容量为1450.0 mg·g^(-1).对CR的吸附动力学方程和吸附等温线模型进行探究,结果表明:纳米复合物对CR的吸附过程符合准二级动力学方程和Langmuir等温吸附模型.该复合物还具有优异的稳定性和可回收性.Organic dyestuff is widely used in daily life and industrial production.However,more and more serious industrial and domestic pollution is resulted due to the excessive use of dyestuff,which poses a major threat to human health.In this study,the bunchy Co_(0.85)Se/Cu(OH)_(2)nanocomposites with multiple nanosheets have been synthesized via one step hydrothermal method.The as-synthesized nanocomposites have high absorptive performance for Congo red(CR)pollutants in wastewater and the maximum adsorption capacity reaches 1450.0 mg·g^(-1) at room temperature.The adsorption kinetics and isotherms of CR have been explored and the results showed that the adsorption process obeys the quasi-second-order kinetic equation and Langmuir isotherm model.In addition,the nanocomposites also displayed outstanding stability and recyclability for removal of CR.
