Optimization of sulfamethazine sodium adsorption onto activated carbon-based Salix psammophila: investigation of adsorption behavior and mechanism

Co-adsorption and interaction mechanism of cadmium and sulfamethazine onto activated carbon surface

“…In the a-d spectra(Fig. 5), the peak at 3445 cm -1 is the characteristic peak of -OH (from phenol or alcohol) and the tensile vibration of water adsorbed on AC [46,47]. The peak at 1412cm -1 is the stretching vibration band of C-O-C, C=C, or C-H on the surface of activated carbon [47,48], the characteristic peak at 1613 cm -1 may be attributed to the C=O tensile vibration on the AC surface [46,47].…”

“…After SMT was adsorbed on AC (c, d spectrum, Fig. 5), there are one or more aromatic rings in the AC structure, corresponding to the pyrimidine ring structure and aromatic ring in SMT [46]. And there is an obvious characteristic peak at 3234 cm -1 , which may correspond to the stretching vibration of -OH [48].…”

Evaluation of Aerogel Spheres Derived from Salix psammophila in Removal of Heavy Metal Ions in Aqueous Solution

“…Li Mei [14] used recycled polypropylene and Salix psammophila powder as the main raw materials and prepared wood-plastic composites with a molding method. Xiao Liu [15] prepared activated carbon-based Salix psammophila with phosphoric acid activation, and the maximum adsorption capacity of the sulfamethazine sodium was found to be 338.58 mg/g. However, there have been few reports on Salix psammophila cellulose adsorbents.…”
