biosorptiota

Biosorption is a process that uses biological materials, such as bacteria, fungi, algae, or plant matter, to remove pollutants from aqueous solutions. This biological material contains functional groups on its surface that can bind to metal ions, organic compounds, or other contaminants through various mechanisms including ion exchange, complexation, and precipitation. The effectiveness of biosorption depends on factors like the type of biosorbent used, the concentration of the pollutant, pH of the solution, contact time, and temperature.

The biosorbents are typically non-living biomass, making the process cost-effective and environmentally friendly compared to conventional methods like chemical precipitation or ion exchange resins. After the biosorption process, the pollutant is removed from the solution, and the biosorbent can either be regenerated for reuse or disposed of safely. Biosorption has shown promise in treating wastewater containing heavy metals like lead, cadmium, copper, and mercury, as well as organic pollutants. Its application is being explored in various environmental remediation contexts, including industrial wastewater treatment and drinking water purification. Research continues to focus on optimizing biosorbent materials and processes for improved efficiency and wider applicability.
