O.A Jonah, D. A Bako

Abstract

The study investigated the optimum conditions for the adsorption of impurities in groundnut oil using commercially activated carbon used for adsorption purposes in nature today is imported and very expensive. The need to get cheaper alternatives is therefore very paramount. Activated carbon used in this research were produced plantain peel – a waste using physical and chemical methods. This was achieved using the standard method of activated carbon production. The produced activated carbon was analyzed for their physicochemical properties as well as bleaching efficiency on groundnut oil. The parameters studied include temperature, contact time and adsorbent dosage on the bleaching performance of the activated carbon on vegetable oil, others parameters studied include: Moisture content, as content, porosity, bulk density, volatile matter content and iodine number. The result for the physicochemical properties of physical activated carbon . And chemical activated carbon were moisture content 3.50± 0.01 and 3.20± 0.11, Ash content 7.50± 0.02 and 6.50± 0.12, Porosity 0.03± 0.04 and 0.02± 0.02, bulk density 0.38± 0.02 and 0.40 ± 0.02, Volatile matter content 33.60± 0.28 and 33.55± 0.38 and Iodine number 523± 0.03 and 654± 0.02 respectively. The groundnut oil 0g, 1g, 2g, 3g, 4g was used to form adsorbent dosage to oil at contact time 15mins, 30mins, 45mins and 60mins for different temperature of 1300C 1400C, 1500C, 1600C, and 1700C. The batch method of adsorption was conducted and the extent of adsorption was measured through UV-Spectrophotometer. The experimental result showed that the optimum bleaching performance is 72% at working conditions of 1500C, contact time of 60mins and adsorbent dosage of 2g thus indicating that activated carbon has potential as bleaching adsorbent. The results of this study showed the activated carbon generated from plantain peels is a good adsorbent for bleaching groundnut oil, this can serve as a means of improving the economy by converting waste to wealth.
