Activated biochar as an adsorbent of organic pollutants for water and wastewater treatment

Abstract

Biomass, especially waste biomass, as an alternative energy source is today's significant issue. Pyrolysis is a process of thermal degradation of raw material, and one of its products is biochar. This product is characterised by high carbon content, and improving its quality through activation allows for its wider use. Chemical activation improves the quality of carbon materials by applying high temperatures and an activator, e.g. KOH. This method allows obtaining sorption materials with a highly developed specific surface area of more than 1100 m2 /g. Pyrolysis of waste biomass, which consisted of corn cobs and cherry stones, was performed. The results of the study of the adsorption capacity of organic pollutants from the aqueous phase by the activated biocarbon are presented. An aqueous solution of Rhodamine B was used as a model pollutant. The study discusses the effect of waste biomass type on organic pollutants' adsorption capacity
