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.

Bamboo-Based Biochar: A Still Too Little-Studied Black Gold and Its Current Applications

Journal of Xenobiotics, Journal Year: 2024, Volume and Issue: 14(1), P. 416 - 451

Published: March 20, 2024

Biochar (BC), also referred to as “black gold”, is a carbon heterogeneous material rich in aromatic systems and minerals, preparable by the thermal decomposition of vegetable animal biomasses controlled conditions with clean technology. Due its adsorption ability presence persistent free radicals (PFRs), BC has demonstrated, among other uses, great potential removal environmental organic inorganic xenobiotics. Bamboo an evergreen perennial flowering plant characterized short five-year growth period, fast harvesting, large production many tropical subtropical countries worldwide, thus representing attractive, low-cost, eco-friendly, renewable bioresource for producing BC. their surface area increased porosity, pyrolyzed derivatives bamboo, including bamboo biochar (BBC) or activated BBC (ABBC), are considered bio-adsorbent materials removing heavy metals, well contaminants from wastewater soil, improving yield. Nowadays, increasing technological applications ABBC include employment energy sources, catalyze chemical reactions, develop thermoelectrical devices, 3D solar vapor-generation devices water desalination, efficient photothermal-conversion devices. Anyway, although it alternative biomass wood produce BC, paving way new bio- circular economy solutions, study bamboo-derived still infancy. In this context, main scope review was support stimulate further studies about possible applications, enlarging current knowledge these allowing more rational, safer, optimized application. To end, after having provided background concerning methods, we have reviewed discussed on reported recent years.
