| Summary: | In this study, two different types of macroporous resins known as XAD-7HP and
HP-20 were evaluated for the adsorption and desorption properties against
bioactive phenolics extracted from Phanerochaete chrysosporium. The study
was conducted at different phase contact time, solution pH and ethanol
concentration by static adsorption and desorption methods. From the results, it
was found that the adsorption capacity for both resins has no significant
difference.Meanwhile in desorption study, HP-20 and XAD-7HP gave 90.52% and
88.28% recoveries, respectively. Then, the kinetic adsorption data were analyzed
with both pseudo-first-order and pseudo-second-order equations and the later
performed better. The adsorption isotherm data were fitted well by both
Langmuir and Freundlich models. |
