Role of Sorbent Surface Functionalities, Partition and Microporosity in 2, 2 ́, 4, 4 ́-Tetrabromodiphenyl Ether Sorption onto Biochars in a Single-Solute System
Abstract:a study was conducted to investigate the sorption behavior and mechanisms of 2, 2′, 4, 4′-tetrabromodiphenyl ether (BDe-47) onto a series of corn straw biochars pyrolysed at 300, 500 and 700°c (Bc300, Bc500 and Bc700). The micropore volume of Bc700 was 34 times higher than Bc300 and Bc500, which indicates that the biochar developed more high energy pore-filling adsorption sites and the carbonization was accelerated as pyrolytic temperatures increased,. The kinetics results showed that the fast sorption rate co… Show more
