【摘要】 以油茶果壳制备的活性炭为吸附剂,探讨了温度、苯酚初始浓度对油茶果壳活性炭吸附苯酚性能的影响,并用两种动力学模型进行了拟合。结果表明:油茶壳活性炭对苯酚的吸附是一个较为快速的过程,60 min就可接近吸附平衡。油茶壳活性炭对苯酚的吸附动力学过程可以用准一级与准二级模型进行很好的描述,相关系数达到0.96以上。更多还原

【Abstract】 Adsorption of phenole at different temperatures and different concentration of phenol by activated carbon, made from the material of oiltea shell,was studied.Determined the adsorption kinetics of phenol onto the activated carbon from oiltea shell and fitted the kinetic data to the first-order equation and the second - order equation.The respective characteristic rate constants were calculated and analyzed.The results showed that the adsorption process was fast and it resched equilibrium at about 60min.The experimental data for the adsorption systems fit well to first - order equation and second - order equation.更多还原
