Objective of this study was to investigate PO₄-P adsorption characteristics of activated palm biochar with application of Langmuir isotherm. For the adsorption experiment of PO₄-P to activated palm biochar, the loading amount of activated palm biochar varied from 0.4 to 6 g L<SUP>-1</SUP> with 30 ㎎ L<SUP>-1</SUP> of PO₄-P solution. The maximum adsorption amount and removal rates of PO₄-P were 0.57 ㎎ g<SUP>-1</SUP> and 56.6%, respectively. The sorption of PO₄-P of activated palm biochar was fitted well by a Langmuir model. For application of Langmuir isotherm, it appeared that the maximum adsorption amount of PO₄-P and binding strength constant were estimated to be 9.36 ㎎ g<SUP>-1</SUP> and 0.005 L ㎎<SUP>-1</SUP>, respectively. Therefore, activated palm biochar can be used to control the release of PO₄-P from supplemented biochar pellet fertilizer.
