Evaluation of adsorption properties of carbon material obtained from pine cone in relation to nitrogen

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.
