Central Composite Design for the Sorption of Crude Oil by Acetylated Pineapple Peel Fibers

Authors: Okpanachi CB, Agbaji EB, Mamza PAP, Yaro SA

ABSTRACT

Oil spillage contamination is a growing environmental concern that harms both terrestrial and aquatic ecosystems, and its clean-up by sorption is an attractive method due to its simplicity and low cost. Extra benefit is accrued when the sorption material utilized is an agricultural waste. In terms of price, environmentally sustainable products and abundance, pineapple peel is an appealing sorbent for this purpose, and chemical modification by acetylation was performed to improve its oil sorption capacity. To determine preliminary ranges of variables in the sorption process, A two-level, four-factor central composite design (CCD) in response surface methodology (RSM) was utilized to analyze the effect of the four process variables namely adsorbent dosage (1.5- 3.5 g), initial oil concentration (25 – 75 g/L), contact time (10-30 min) and temperature (25 oC – 45 oC) on the oil sorption capacity. Based on the design, a total of 30 sorption experiments were performed and a quadratic model was developed linking the process factors to the response. From the analysis, the interaction plot and cube plot showed higher sorption capacities of the treated (acetylated) compared to the raw fibers. Results from the Analysis of variance (ANOVA) also indicated that the model of the treated fibers was more adequate than the raw fibers.
