简介：为孔雀石绿色(MG)从工业pyrolytic轮胎字符(APTC)生产的激活的碳的吸附特征上的小organics的影响被一个批方法调查。酚被选择为小organics的代表。吸附平衡，动力学和热力学上的酚的效果系统地被学习。结果显示APTC是为MG的潜在的吸附物。酚减少的存在为MG的APTC的吸附能力，但是，改进吸附的率吸附特征动力学和热力学例如平衡，没被酚影响。吸附平衡数据跟随兰米尔等温线和运动数据被pseudo-second-order很好描述运动模型。吸附过程跟随intra粒子散开模型，吸附率由超过一个过程是坚定的。热力学的学习证明吸附是一个吸热、自发的physisorption过程。
