Estudo da reten??o de íons cromo por gibbsita e peneira molecularDOI: 10.1590/S0100-46702011000100009 Keywords: chrome, retention, gibbsite, molecular sieves. Abstract: herein we report the employment of the gibbsite and a commercial sieves on the retention of the chromium ions on different concentrations, temperatures and lay times. the results of those experiments plus those of the lixiviation processes show that both stationary phases present a high ratio of retention and resistance against leaching.
