  • In the present study, nanochitosan emulsion has been produced in a suspension form by adding tripolyphosphate solution into a chitosan solution drop-wise. The adsorption capacities of four acid dyes, namely, Acid Orange 10 (AO10), Acid Orange 12 (AO12), Acid Red 18 (AR18) and Acid Red 73 (AR73) on nanochitosan, have been determined to be 1.77, 4.33, 1.37 and 2.13 mmol l(-1), respectively. The nanochitosan dye capacities were compared with normal chitosan capacities which were 1.54, 2.66, 1.11… CONTINUE READING
