Sorbent Textiles for Colored Wastewater Made from Orange Based Pectin Nano-hydrogel

In this article, the synthesis of pectin nano hydrogel, it's having high absorption ability and its related applications in the treatment of colored wastewater have been investigated. Pectin has been extracted from orange peel as a good source of pectin and the degree of esterification (DE) of pectin as a main parameter on the gel formation were determined. Pectin nano hydrogel was synthesized using Calcium Chloride as a cross-linking agent. The nanometer size and dye adsorption ability of hydrogel particles from colored wastewater have been confirmed by the SEM and UV-Vis spectroscopy methods, respectively. At the next step, the dye adsorption ability of the treated polyester fabrics with pectin nano hydrogel was assessed and results indicated the high adsorption capacity of synthesized nano hydrogel. More specifically the spectrophotometry method indicated that treated polyester fabrics with chitosan and pectin nano hydrogel showed more dye absorption in compare to pectin and cationic surface agent treated fabrics.
