Adsorption and biosorption for pollutant removal

Adsorption and biosorption research examines how contaminants in water and wastewater bind to solid materials, allowing pollutants such as heavy metals, synthetic dyes, and emerging chemicals to be captured and removed from solution. The process turns on physical properties of the sorbent—particularly surface area and pore structure—which determine how much contaminant a material can hold and how quickly it captures it; biochar derived from agricultural waste and various nanomaterials have drawn particular attention as low-cost, high-performance options. A central practical challenge is translating laboratory-scale isotherm and kinetic data into reliable predictions for real, mixed-contaminant wastewater streams, where competing solutes and variable conditions complicate performance. Researchers are also working to understand the mechanisms behind biosorption—the uptake of pollutants by microbial or plant-derived biomass—well enough to engineer more selective and regenerable materials for full-scale treatment systems.
