What are the main phenolic acids and how are they adsorbed on SiO2-NH2-FPBA?

Label:chem

Topic
A study investigates the adsorption properties of a novel phenylboronic acid and amino bifunctional modified silica gel (SiO2-NH2-FPBA) for phenolic acids, including gallic acid (GA), caffeic acid (CA), and protocatechuic acid (PCA). These phenolic acids are important secondary metabolites in medicinal plants and have significant biological activities.
Answer
The adsorption capacities of SiO2-NH2-FPBA for GA, CA, and PCA were 79.66 mg/g, 93.64 mg/g, and 89.35 mg/g, respectively.
