Salvianolic acid A (SAA) has high pharmacol. activity and is widely used in the treatment of various diseases. We reported herein a strategy for effective adsorption of SAA from aqueous solution by surface molecularly imprinted magnetic nanoparticle (SIMNP). 4-(acryloyloxy)phenylboronic acid, 1-vinylimidazole and methacrylamido Pr tri-Me ammonium chloride were chosen as functional monomers. 1-vinylimidazole not only neutralizes the acidity of SAA solution to help phenylboronic acid react with ortho-phenolic hydroxyl groups of SAA quickly and stably, but also captures SAA through electrostatic interaction and hydrogen bond. Besides, the introduction of pos. charged methacrylamido Pr tri-Me ammonium chloride can accelerate the adsorption kinetics. Adsorption kinetically follows a pseudo-second-order model and achieves equilibrium within 10 min at 298.15 K with high selectivity. And the maximum adsorption capacity can be determined to be 1117.6 mg/g by Langmuir adsorption model. Adsorption mechanism involves the formation of covalent bond, electrostatic interaction and hydrogen bond. This work indicates that SIMNP is a promising adsorbent to realize effective capture of SAA from aqueous solution In the experiment, the researchers used many compounds, for example, (4-((4-Methoxybenzyl)oxy)phenyl)boronic acid (cas: 156635-90-4Computed Properties of C14H15BO4).
(4-((4-Methoxybenzyl)oxy)phenyl)boronic acid (cas: 156635-90-4) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Computed Properties of C14H15BO4
