Abstract:
The pine cone, solid waste was successfully converted into activated
carbon using chemical agents H3PO4. Their properties including porous structures,
surface functional groups and morphology structures were carefully studied. The N2
adsorption studies showed that the nitrogen isotherm exhibits Type IV, and the
presence of hysteresis loop clearly shows the predominantly mesoporous
characteristics. The values of correlation coefficient R2 = 0.9999 represented the
satisfactory pseudo-second-order model. The results show that pine cone activated
carbon was effectively used as adsorbent.
