Effect of ph on adsorption of organic acids and phenolic compounds by amber lite ira 67 resin
Haslaniza Hashim1, Wan Yaacob Wan Ahmad2, Saiful Irwan Zubair3, Mohamad Yusof Maskat4.
Adsorption of model solution containing organic acids (octanoic and
hexanoic acid) and phenolic compounds (rutin, scopoletin and quercetin)
on a weak base anion exchange Amberlite IRA 67 resin was studied in a
model system. This research was carried out to understand the effect of pH
on single and multicompounds studied for its further use in actual system (fruit
system). It was shown that the pH dependence of adsorption capacity of
weak base anion exchange Amberlite IRA 67 resin had similar increasing
trend on organic acids (hexanoic and octanoic acid) and phenolic
compounds (rutin, scopoletin and quercetin) studied as pH values increased.
In single solution of each phenolic compound, it was observed that total
phenolic content (TPC) and antioxidant activity (FRAP and DPPH) gave
highest values closer to neutral pH regime. The pH dependence of
adsorption capacity in multicompounds solution also showed similar trend for
organic acid compounds. Similar trend was also found in multicompounds
solution of phenolic compounds in total phenolic content (TPC) and
antioxidant activity (FRAP and DPPH). The findings obtained in this study will
help to gain better understanding of the complex mechanisms of ion
exchange resin and adsorption process involving multicompounds system.
