Poplar hydrochar (RHC) was activated by thermal oxidation (TA-O) in air at 300 °C (O30 and in air + N2 (0.5% O2) at 500 and 700 °C (O500 and O70, respectively, and in N2 at 300-700 °C (N300-N70 as control. Samples characterized by various methods were used to analyze their effect on tetracycline adsorption. The results showed that TA-O greatly increased adsorption capacity qe, 100 (mg·g-1, C0 = 100 mg·L-1) from 6.29 for RHC to 33.32, 96.23 and 60.90 for O300, O500 and O700, respectively. The O300 increased carboxyl and aromaticity whereas little influ
