| 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. |
