Interactions between benzotriazole and corncob biochars pyrolyzed at different temperature
Benzotriazole Biochar H-bond Micropore filling
2018/3/23
The sorption of ionizable benzotriazole (BTA) to corncob biochars pyrolyzed at different temperature (i.e., 300 oC, 500 oC and 800 oC) was investigated in this study. Biochars produced at higher tempe...
