ADSORPTIVE PERFORMANCE OF BIOCHAR FROM CASSAVA PEEL ON INDIGOSOL BLUE 04-B DYE IN BATIK WASTEWATER

The study investigates the capacity of biochar from cassava peel (BCP) to work as an adsorbent to get rid of Indigo sol Blue 04-B dyes in Batik wastewater. BCP is produced through a pyrolysis process at temperatures of 300oC, 400oC, and 450oC. The research explored the adsorption characteristics of BCP under varying experimental conditions, including pH variations, weight, and contact time. The adsorption process was examined by assessing factors such as absorbance, initial concentration, equilibrium concentration, and the percentage of dye adsorbed. The results show that BCP adsorbs Indigo sol Blue 04-B dyes with considerable efficiency, significantly influenced by pH levels of 7.0, BCP weight of 75 mg, and contact time of 40 minutes, achieving adsorption capacities of 72.16%, 51.07%, and 63.50%, respectively. The results show that BCP has a lot of potential as an effective adsorbent for getting rid of Indigo sol Blue 04-B dyes. This study demonstrates the significance and positive implications of environmentally friendly waste treatment, inexpensive and efficient alternative adsorbents, and improved waste quality.
