Using raw bamboo waste to sustainably remove toxic dyes from water

Akash Rathod, Michigan, USA 16-18

Anionic dyes are commonly used in the textile industry, with effluents contributing to global water pollution. Current dye removal techniques are inefficient and expensive, infeasible for use in developing countries. Raw bamboo waste was used to form cationized dialdehyde cellulose, a cheap and biodegradable adsorbent that was tested to remove congo red (an anionic dye) from wastewater. Multiple parameters were tested, including dye concentration and contact time. The adsorption kinetics were modeled by pseudo-first-order and pseudo-second-order kinetics, and the Langmuir and Freundlich isotherm models were applied. Promising adsorption results were obtained, with an adsorption capacity of 909.09 mg/g.
