Abstract:
ranian researchers at Amir Kabir University of Technology and Institute for Color Science and Technology produced a bio-adsorbent with very high performance for the removal of dye from textile wastewater by preparing a combination of chitosan and dendrimer nanostructure.
Among the unique characteristics of these bio-adsorbents, mention can be made of high adsorption capacity, biodegradability, biocompatibility and non-toxicity.
The aim of the research was to produce chitosan-dendrimer combination in order to remove dye from the wastewater containing reactive dyes. To this end, chitosan was modified in the first step by using ethylacrylate. Then in the second step, chitosan-dendrimer combination was produced by using PPI second generation of dendrimer.
Parameters that affect the dye removal process including pH, concentration of dye, time and temperature of contact were studied by RSM program in order to optimize the process. Kinetic studies and adsorption isotherms at equilibrium were evaluated too in order to measure the amount of dye adsorbed on the adsorbent.
Results showed that chitosan-dendrimer polymer bio-adsorbent could be used as a high potential and biodegradable bio-adsorbent to remove anionic compounds such as reactive dyes from textile industry wastewater. High adsorption capacity, biodegradability, biocompatibility, and non-toxicity are among the unique properties of these adsorbents.
Results of the research have been published in details on 15 February 2013 in Journal of Applied Polymer Science, vol. 127, issue 4, pp. 2607-2619.
