Preparation of carboxymethyl cellulose/chitosan-CuO giant vesicles for the adsorption and catalytic degradation of dyes

Composite beads from chitosan and zeolitic imidazolate framework-8 for the adsorption and photocatalytic degradation of reactive red 141

“…The decomposed products and residual dyes occupy the surface, reducing the photocatalytic degradation efficiency. 56 …”

“…13(a) ). 61 For fresh ZnO/CS + CIT + 2.5% ZIF composite beads, the diffraction peaks of ZnO were observed at 31.8°, 34.4°, 36.2°, 47.5°, 56.5°, 62.7°, 66.4°, 67.9°, and 69.1° corresponding to the hexagonal phase of the wurtzite structure of ZnO. 62 The diffraction peaks of ZnO/CS + CIT + 2.5% ZIF composite beads after the 10th cycle matched well with those of the fresh sample.…”

“…The decomposed products and residual dyes occupy the surface, reducing the photocatalytic degradation efficiency. 56 The photocatalytic degradation efficiency can also be reduced if ZnO is dissolved into Zn 2+ or decomposed. ZnO particles are photo-decomposed under irradiation, and the decomposition increases with the irradiation time.…”

Synthesis and Applications of Carboxymethyl Cellulose Hydrogels

“…In addition to their application in medical fields as anti-tumor and bacteriostatic agents, hydrogels have applications in agriculture [ 56 , 57 , 58 ], wound healing [ 59 ] and other fields [ 60 , 61 , 62 , 63 ].…”

One-step construction of silver–polyaniline nanocomposite modified multifunctional sponges for wastewater remediation: adsorption, catalysis and antimicrobial applications

“…The resulting adsorbent-dyes are usually processed by conventional chemical regeneration or electrochemical-assisted desorption, and high concentrations of organic wastewater are generated during the regeneration of spent adsorbents, which may cause secondary contamination and additional treatment costs. 20 Combining with advanced oxidation would be one of the solutions to avoid these problems.…”
