Abstract

Production of carbon adsorbent from agricultural waste (apricot stones) and its application for water purification from organic pollutants are investigated in the paper. Activated carbon (AC) is prepared by pyrolysis of the biomass materials at 700 °C in a flow of steam. Steam pyrolysis is a process, which creates both energy liquid and gaseous products, as well as high-grade activated carbons. The produced AC as solid product is used for removal of phenol and p-nitrophenol. It was found that the adsorption capacity is 152. mg/g for phenol and 179. mg/g for nitrophenol. An hybrid adsorptive-membrane purification of water from phenol is performed, and it is established that this combination considerably increases the effectiveness of the water purification from phenol.
