Abstract :
In present work, orange peel derived activated carbon (OPAC) loaded into poly (styrene-co-butyl acrylate) green composites were synthesized with different weight fractions of (OPAC) viz.,0, 2, 5, 8, and 10 wt% filler in the biocomposites. The effect of different water activity (aw) on the moisture sorption of Orange Peel Activated Carbon (OPAC) filled poly (styrene-co-butyl acrylate) green composites was investigated. Moisture sorption was carried out by exposing the composite specimens to different water activity (aw) from 0.1 to 0.9 at 25 °C. The obtained sorption data were used to fit five different sorption isotherm models; namely, Braunauer-Emmet-Teller (BET), Smith, Halsey, Caurie, and Oswin proposed in the literature. The model constants were determined by linear fitting of the sorption equations. The value of the coefficient of determination (R2 = 0.99) confirms the linear fitting of the equations studied.
