Binding of cadmium on raw paper pulp. Relationship between temperature and sorption kinetics
Several assays have been carried out in order to study in detail the cadmium mobility from water to virgin pulp as previous step of cadmium mobility description from paper into food. Virgin pulp has been immersed in different concentration aqueous solutions at several temperatures and during short and long time. The absorbed cadmium amounts have been measured by atomic absorption spectroscopy. For a long time, the temperature of storage is not an important factor except during the first 3 h. In general, percentage of migrated cadmium into pulp is between 30% and 90% of initial charge. Kinetic equation of cadmium mobility has been described employing statistics methods with a very good correlation. © 2002 Elsevier Science Ltd. All rights reserved.
