In addition, the number of lactone groups (-COOR), phenolic hydroxyl groups (-OH), and carboxyl groups (-COOH) on the surface of biochar gradually decreases as the temperature of biochar increases, while the number of carbonyl groups (-C = O) gradually increases, but the total amount of acidic oxygen-containing functional groups shows a decreasing trend, which is consistent with the FTIR analysis results of biochar.
