Clean and Green Bamboo Magic: Recent Advances in Heavy Metal Removal from Water by Bamboo Adsorbents

Water, Journal Year: 2025, Volume and Issue: 17(3), P. 454 - 454

Published: Feb. 6, 2025

Adsorbents derived from bamboo, such as biochar, charcoal, activated carbon, and chemically modified are recognized for their efficiency cost-effectiveness in removing heavy metals water. Despite this, there remains a gap applying bamboo-based adsorbents treating metal-contaminated water sources, particularly regarding physicochemical properties, adsorption mechanisms, modifications. This review highlights the influence of factors specific surface area, pore distribution, pH, cation exchange capacity, elemental composition, functional groups on ability bamboo to adsorb metals. It also discusses recent advancements enhancing properties through physical chemical modifications examines how variables like adsorbent dosage, temperature, initial concentrations cations, affect metal removal. The categorizes mechanisms into complexation, adsorption, electrostatic interaction, ion exchange, precipitation, redox effect. While have shown higher sorption capacity laboratory settings, is need more comprehensive studies optimize performance, scalability, real-world applications.
