In the present work, a novel composite CCF@UiO-66-NH2@TpBD (CCF stands for carboxyl cotton fiber) was fabricated for the extraction and removal of BPs from aqueous samples. Both the UiO-66-NH2 (MOF) and TpBD (COF) were immobilized on CCF through feasible layer-by-layer and Schiff base reaction, and characterized using field emission SEM (FESEM) equipped with energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform IR spectroscopy (FT-IR), and XPS techniques. The CCF@UiO-66-NH2@TpBD was packed in pipet tip as micro-column to investigate the adsorption of BPs using a pipet tip solid-phase extraction (PT-SPE) method. Various parameters (sampling flow rate, sample pH, amount of adsorbent, ionic strength, methanol concentration, and flow rate of eluent) affecting the extraction efficiency were optimized. Based on strong π-π conjugation, hydrogen bonding, and hydrophobic interactions, the adsorbent exhibited good extraction and removal capability. A low limit of detection (0.16-0.75 ng/mL) and a high adsorption (4.3-5.6 mg/g) were obtained. Accordingly, the composite CCF@UiO-66-NH2@TpBD material was shown to be a suitable adsorbent for the extraction and removal of BPs from aquatic samples due to excellent reusability, reproducibility, and high adsorption capacity. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Recommanded Product: 620-92-8).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 620-92-8
