Oxidized cellulose (oxycellulose) was very effectively used in the form of filter sheets to remove some metal ions from water and from aqueous solutions. Furthermore; oxycellulose was applied in an ion-exchange column and in a batch process. The mechanisms of the sorption process inside oxycellulose as well as the kinetics of sorption were studied. A comparison of oxycellulose and other adsorption components such as zeolites and ion-exchange resins was made. The affinity of oxycellulose to metal ions was determined to be in the following order: Cd2+; Zn2+2+ » Ca 2+2+ » Na+. The use of oxycellulose was very effective; especially in the form of sorption filters; because this allowed us to use a simple filtration process. Moreover; the specific loading amount of the filter cake was higher for filtration than for the column process under comparable conditions. Oxycellulose in a glass column behaved similarly to an ion-exchange resin. It showed approximately constant efficiency until the sorption capacity of the adsorbent was exhausted; and then it suddenly dropped. © 2009 Wiley Periodicals; Inc;
