以椰壳为原料制得活性炭C-1,采用KOH活化法对C-1改性得到活性炭C-2,通过红外分析仪、扫描电镜、粉末衍射仪等仪器对C-1和C-2进行表征。结果表明,C-2含有较多的含氧官能团,会形成新的孔隙;以铀(VI)溶液为研究目标,C-1对铀的吸附量为3.01mg/g,C-2对铀的吸附容量为3.62mg/g,Lagergren准二级动力学方程和Langmuir吸附等温式能很好的描述C-1和C-2对铀(VI)的吸附。

Activated carbon C-1 was prepared from coconut shell,and activated carbon C-2 was obtained by modification of C-1 by KOH activation method.The characterization methods adopted by C-1 and C-2 are mainly through infrared analyzer,scanning electron microscope,powder diffractometer and other instruments.The results show that C-2 contains more oxygen-containing functional groups and forms new pores.Taking uranium(VI)solution as the research target,the adsorption capacity of C-1 for uranium is 3.01mg/g,and the adsorption capacity of C-2 for uranium is 3.62mg/g.The Lagergren quasi-second-order kineti...
