What is the role of acetic acid (CH3COOH) in the desorption process of phenolic acids from SiO2-NH2-FPBA?

Label:chem

Topic
A study explores various desorption conditions to recover phenolic acids from SiO2-NH2-FPBA. The effectiveness of different acidic solutions in desorption is evaluated.
Answer
Acetic acid (CH3COOH) at pH 2 is the most effective desorption agent, recovering over 90% of the adsorbed phenolic acids. It does not destroy the structure of the phenolic acids, ensuring their integrity for further use.
