Using the HPLC apparatus sthdy the DMP adsorption/desorption characteristic on two carbon adsorbents, then fitting the isotherm and kinetics curves. The results show that:the qe of Donghai ash is lower than Shishou ash in different temperature; in the isotherm fitting curves, the Freundlich fitting coefficient n is less than 1, therefore both of the two adsorotion process of different adsorbent behave as non-linear adsorption; the△H of two adsorption processes are negative, this indicate the processes are exothermic reaction; the fast adsorption stage of Shishou ash use less time than the other; the desorption processes are behave as non-linear adsorption.

使用高效液相色谱仪研究两种炭质吸附剂对邻苯二甲酸二甲酯的吸附/解吸特性,并对实验结果进行等温线拟合和动力学拟合,结果表明：在不同温度下的吸附实验中,市售草木灰对邻苯二甲酸二甲酯的单位吸附量均大于东海生物质灰；在等温线拟合中,Freundlich拟合系数n均小于1,说明两种草木灰的吸附均表现为非线性吸附；两种吸附剂的吸附热均为负值,表明吸附过程为放热反应；市售草木灰的“快速吸附”阶段时间更短；邻苯二甲酸二甲酯从东海生物质灰和市售草木灰解吸均为非线性过程。
