Biochar derived from different crop straws as persulfate activator for the degradation of sulfadiazine: Influence of biomass types and systemic cause analysis

Popis výsledku v původním jazyce

In order to study the effect of biomass types on the catalytic activity of biochar, six kinds of biochar prepared from six common crop straws were used for persulfate activation to degrade sulfadiazine (SDZ). The SDZ removal rates of biochar samples from sorghum, reed, cotton, rape, sesame, and soybean stalks were 94,4%, 85,1%, 68,4%, 46,2%, 43,6%, 36,6%, respectively, their catalytic performances were significantly different. The six biochar samples were systematically characterized, and differences in their persistent free radicals, dissolved organic matter, oxygenated functional groups, as well as carbon configuration were found. The degradation mechanism was studied by identifying active species and electrochemical experiments. It was concluded that sulfadiazine was decomposed through nonradical pathways in all biochar + persulfate systems. The graphitic carbon in biochar acted as an electron shuttle for direct electrons transfer from sulfadiazine to persulfate, which mainly contributed to the de
