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.展开更多

Their structures have been confirmed by elemental analysis, IR, 1H NMR and MS. The compounds were found to have antianemic activity. The RBC and HB values of the tested anemic rats were increased by 72 0% and 126 4%, respectively after abdomen injection.展开更多
