The combined adsorption and partition effects of biochars with varying fractions of noncarbonized organic matter have not been clearly defined. Biochars, produced by pyrolysis of pine needles at different temperatures (100−700 °C, referred as P100−P700), were characterized by elemental analysis, BET...
