In this work, the effect of cross-linking of chitosan beads on the removal efficiency of dye RB 5 from aqueous solutions was defined. In the studies not crosslinked chitosan as well as chitosan cross-linked with a chemical cross-linking agent - glutaraldehyde and ionic cross-linking agent - pentasodium tripolyphosphate were used. The scope of the research included the determination of pH at which...
This study investigated the effectiveness of phosphate adsorption onto non-cross-linked chitosan beads [CHs], and onto chitosan beads cross-linked with glutaraldehyde [ALD-CHs] and epichlorohydrin [ECH-CHs]. The weight ratio of glutaraldehyde to chitosan was 1:2 (w/w), whereas that of epichlorohydrin to chitosan was 2:1 (w/w). The optimal pH value of the phosphate adsorption process was determined...
