The adsorption isotherms for polymer adsorbent H103 with aniline from aqueoussolution are carried out by steady and nonsteady method. It is found that adsorption isotherms fitFreundlich Eq better than others. The breakthrough curves are determined byC/C0 and it can be used for continuous operation on microcomputer. A mathematical model for fixed-bedadsorber of H103 polymer adsorbent with aniline in solution was built up, and can be used forcontinuous operation on microcomputer. The analysis of experiment results show that it is necessary thatthe time T of the aniline aqueous flowing through fixed-bed should be longer than the time foradsorption balance, otherwise the computing letngth of the fixed-bed will be smaller than practice oneneeded.
