INVESTIGATION OF THE REMOVAL OF REACTIVE BLUE 220 DYE BY GUM EXTRACTED FROM TARAMIND SEEDS

Tóm tắt

In this study, gum was successfully extracted from tamarind seeds (gum) and used as a material for removal of reactive dye (Reactive Blue 220-RB220). The performance of decolorization and COD reduction of gum was investigated using one-factor-at-a-time method. The factors include pH, mixing time, agitating speed, color concentration, and gum concentration. Under optimal conditions, color and COD removal efficiency of gum was roughly 74.4% and 83.3%, respectively. These results indicate that gum is a “green” and “eco-friendly” coagulant and has great potential for application in textile dyeing wastewater treatment.
