Sorption Wastewater Decolorization by Biopolymer

Abstract

The article shows the possibility of using solid production waste for sorption decolorization of wastewater from textile enterprises. It was proved that leather shavings have the best ability to absorb water-soluble dyes in a stationary mode among other traditional adsorbents of silica gel, zeolite, shungite, clays, activated carbon (dye absorbtion in a stationary mode is 99.6%). Leather shavings absorbtion capacity of various dyes was calculated in dynamic mode. Leather shavings high efficiency in reducing the spent solutions colorization of mono and mixed color solution was confirmed. Confirmed reuse of leather shavings to absorb dyes.
