The effect of early posthatch local feed in pectoralis muscle of Jawa Super chicks (Gallus gallus domesticus) AIP Conference Proceedings 1755, 140003 (2016) Abstract. The study aimed to obtain of palm kernel shell activated carbon (PKSAC) potentially as an adsorbent for recovery of β-carotene from crude palm oil. Activation of palm kernel shell carbon was done chemically using phosphoric acid at impregnation ratio of 3 (ml/g) for 24 hours and carbonization at 500 o C for 30 min and 60 min called PKSAC30 and PKSAC60 respectively. The results showed that the yield of PKSAC30 and PKSAC60 were 48.82% and 47.67%, the surface area were 1665.823 and 1680.877 m 2 /g respectively, whereas surface area of decolorized activated charcoal (DAC) as control activated carbon was 1068.391 m 2 /g. PKSAC30 able to adsorb β-carotene in isopropyl alcohol at the equilibrium as much as 14.32 mg/g, while the DAC as much as 21.58 mg/g. Desorption of β-carotene from DAC using tetrahydrofuran reached 49.99%, while from PKSAC30 reached 28.30%.

Adsorption of β-Carotene in Isopropyl Alcohol with Decolorized Activated Carbon as Model for β-Carotene Adsorption in Crude Palm Oil

“…The total pore volume of the DAC reaches up to 0.9523 cc/g [13]. Mesopore size distribution for DAC at 77.3 K is presented in Fig.…”

“…Porosity characteristics of DAC include the pattern of N 2 adsorption isotherms and surface area of DAC had been published [13]. From the pattern of N 2 adsorption isotherms showed a mix of type I and IV isotherm, characterizing the micro-and mesopores.…”

“…Decolorized activated carbon (DAC) from Sigma is one of the adsorbents can be used to decolorize liquids. The DAC characteristics which include the pattern of N 2 adsorption isotherms and Brunauer-Emmet-Teller (BET) surface area had been published [13]. The pattern of N 2 adsorption isotherms indicated that the DAC has a lot of mesopore with a BET surface area of 1068.391 m 2 /g, but mesoporosity and surface functional groups of DAC have not been published.…”

“…The pattern of N 2 adsorption isotherms indicated that the DAC has a lot of mesopore with a BET surface area of 1068.391 m 2 /g, but mesoporosity and surface functional groups of DAC have not been published. The potency of DAC to adsorb of β-carotene had been studied [13]. The DAC can adsorb β-carotene up to 21.56 mg/g.…”
