Technical Abstract: Controlling of water pollution has become increasingly important in recent years. The release of synthetic dyes into the environment constitutes only a small proportion of water pollution, however, due to their brilliance even smaller quantities can have a visible impact. Many dyes are difficult to decolorize due to their complex structure and synthetic origin. The adsorption or sequestration of reactive dye Remazol Brilliant Blue R (RBBR) by a Polyelectrolyte Complex (PEC) was studied in a batch system and the adsorption parameters were determined. Specifically, studies were conducted to examine the impact of pH variation and time required for the adsorption of dye (in mg g-1) by the PEC complex. The data indicated that the adsorption capacity of PEC was pH sensitive and greater dye sequestration occurred at pH ranging between 8-11. The maximum adsorption of 50-ppm dye solution was roughly 88.52% equal to 5.901 mg of dye/g of polymer. Furthermore, the amount of dye adsorbed by the PEC increased with time initially, and then reached a plateau within 15 minutes as an optimal contact time. The biobased PEC's show the capacity and potential for removing synthetic dyes from waste water generated during industrial processing of paper and textile.
