The removal of crystal violet dye using plant-based sorbents / Nurhana Lee Hai Liang @ Kasman

The widespread use of crystal violet dye in the textile industry has led to significant wastewater pollution, posing a threat to safe drinking water worldwide. This pollution affects human health and aquatic life by contaminating fresh body water and reducing dissolved oxygen levels through the inhibition of photosynthesis metabolism. Additionally, traditional waste management methods, such as open burning, contribute to air pollution. To address these issues, adsorption using plant-based sorbents has emerged as an effective technique. This project aims to prepare sorbents from banana peels (BP), pineapple wastes (PW) and sugarcane bagasse (SCB) and evaluate their effectiveness in removing crystal violet dye. The study will investigate the impact of concentration, pH, and contact time on the dye removal process. The anticipated outcomes include insights into the preparation of plant-based sorbents and a comprehensive understanding of their performance in dye removal.
