Their structures were confirmed by elemen\|tal analysis, IR, 1H NMR, UV and MS. Some of these compounds showed antitumor activities in vitro.展开更多

The results show that the coordination could increase the thermal stability of the cellulose and the adsorption occurs through a chelating reaction between Cd 2+ and O of OH from cellulose and S from pyrrolidine thiocarboxylic acid.展开更多
