Layer interaction adsorption isotherms model of mango seed as biosorbent in reducing free fatty acid and peroxyde value in crude palm oil refining

The activated mango seed was used to reduce FFA (Free Fatty Acid) and PV (Peroxyde Value) content in CPO (Crude Palm Oil). This study was begun with biosorbent modification. With size 140 mesh, 1% biosorbent of CPO with 35 minutes contact time, and shaking speed 200 rpm shown that the FFA and PV red...

Description
Summary:The activated mango seed was used to reduce FFA (Free Fatty Acid) and PV (Peroxyde Value) content in CPO (Crude Palm Oil). This study was begun with biosorbent modification. With size 140 mesh, 1% biosorbent of CPO with 35 minutes contact time, and shaking speed 200 rpm shown that the FFA and PV reduction percentage were 28.97% and 51,6%. The surface layer interaction model results follow Freundlich isotherm. The R2 of kinetics equation model results are 0.9879 on FFA adsorption and 0.9923 on PV adsorption. This model involves the assumption that the pore surface of the biosorbent is different or heterogeneous. The Freundlich Isotherm model is also based on the assumption that there is a pore size distribution on the adsorbent and is applicable to more than one surface layer (multilayer) adsorbed by biosorbent. The ability of activated mango seed to adsorb more organic compound shows its potential as an alternative for bleaching earth substitute.
