Adsorption of Water Pollution by Biochar Produced from Biomass

Abstract

Biochar is produced from lignocellulosic biomass (wood, agricultural and forestry waste, etc.) through thermal decomposition at high temperature. Water pollution (pesticides, dyes, heavy metals, and volatile organic compounds [VOCs]) can be efficiently removed by biochar. In particular, waste biomass is typically used as fuel or thrown away; thus, it is necessary to determine a valuable utilization for it. The process of biochar production is simple and suitable for the production of porous structures. In this paper, 1) biochar production and its characteristics based on biomass types, 2) research trends on the adsorption of water pollution (pesticides, dyes, heavy metals, VOCs) on biochar, and 3) expected effects are discussed.
