EFFECTIVENESS OF DYE ADSORPTION ONTO NON-CROSS-LINKED AND CROSS-LINKED CHITOSAN BEADS
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2012, Vol 0, Issue
Abstract
The study was established to analyze the effectiveness of Reactive Black (RB5) and Basic Green (BG4) dyes adsorption onto chitosan beads and onto chitosan beads cross-linked with glutaraldehyde depending on the initial dye concentration in the solution (1, 5, 100 and 200 mg/dm3). It demonstrated that both the initial concentration of dye in the solution as well as the type of adsorbent affected the effectiveness of the adsorption process. An increase in the initial dye concentration in the solution was increasing adsorption effectiveness, irrespective of the type of dye and adsorbent. The cross-linking of chitosan beads with glutaraldehyde turned out to be beneficial only in the case of the RB5 dye.
