Biosorption of Mercury by Reed ( Phragmites australis ) as a Potential Clean Water Technology

摘要: Heavy metals are causing serious environmental and health problems worldwide, especially in places where mining is one of the major drivers country’s economy. Conventional technologies considered expensive when providing safe water; for this reason, new clean water needed. Biosorption has gained attention as a cost-effective system that uses biological materials to remove heavy from however, it can be noted an efficient proven biosorbent several metal not been found. Reed (Phragmites australis) demonstrated potential because commonly found accumulator wetlands. This study focused on mercury (Hg) removal by using reed biosorbent. Batch experiments were conducted microstructure was analyzed scanning electron microscope. The Langmuir isotherm Freundlich model applied data obtained. pseudo-first-order pseudo-second-order models used test adsorption kinetics investigate mechanism biosorption. A comparison with performance various adsorbents reported literature made. results contribute understand use Phragmites australis biomass technology since removed effectively high concentrations. supports variety researches achieve technologies, biosorption proved useful alternative conventional systems ions aqueous solution.
