Determination of O-containing functional groups distribution in low-rank coals by chemical titration

Distribution of oxygen-functional groups (carboxyl, alcohol-hydroxyl, phenol-hydroxyl, methoxyl and carbonyl) in 4 Chinese low-rank coals was evaluated based on chemical analysis. Concentration of carboxyl was quantitated by acetic acid calcium ion exchange method and the buffer (pH=8.3). The effect...
