Adsorption isotherm determination and heavy metal removal by acid-washed softwood biochar

Conference Dates

August 20-25, 2017


Heavy metal concentrations above critical range in soils may pose environmental and economic problems by hindering plant growth and limiting land usage. Biochar used as soil amendment is a low-cost, natural remediation technique, which has the capability to immobilize and reduce metals (exchangeable, oxide-bound, and organic matter-bound) bioavailable for plant uptake. Its large surface area provides high capacity for binding metals through sorption reactions.
