Abstract

This research was carried out to determine the effect of chitosan concentration in synthesising crosslinked tripolyphosphate (TPP) macropore beads on turbidity, dye content, and Chemical of Demand (COD) Sasirangan wastewater. Macroporous chitosan-TPP beads were synthesised from chitosan solution with various concentrations of 2%, 3%, 4%, and 5% and added NaHCO3 as a porogen, then dripped into 0.75% tripolyphosphate solution. It was further interacted with Sasirangan wastewater by adsorption method with its effect analysed by using the turbidity value, dye content, and COD. The results showed that beads with a 3% chitosan concentration were the most effective in reducing the turbidity, dye content, and COD value. Furthermore, using a more than 3% chitosan concentration indicates reduced effectiveness. Macroporous Chitosan-TPP beads were able to produce a decrease in turbidity, dye content and COD by 81.21%, 55.44%, and 59.37%.
