CuO与碱改性椰壳活性炭吸附苯的实验研究
An Experimental Study on the Adsorption of Benzene Utilizing CuO and Alkali-Modified Coconut Shell Activated Carbon
摘要
Abstract
A novel adsorption material,KOH-C/CuO,was synthesized through the impregnation method using coconut shell activated carbon as support.The surface physical and chemical properties of the material were characterized by SEM,BET,FTIR,and XPS analysis.Subsequently,a benzene adsorption experiment was conducted to evaluate its performance.The influence of KOH concentration,modification time,CuO load(mass fraction),and adsorption temperature on the benzene adsorption properties was systematically investigated.Furthermore,a comprehensive evaluation of the materials'adsorption properties was carried out.The results indicated that the adsorption performance of 0.5K-C-4/CuO-3 reached its peak when the KOH concentration was 0.5 mol/L,the modification time was 4 h,the CuO load was 3%,and the temperature was maintained at 25℃.The adsorption capacity for benzene achieved a remarkable value of 235.3 mg/g,surpassing unmodified material by 118.88 mg/g.关键词
