A facile rapid-combustion process was introduced for preparing magnetic CoxMgyCu(1-x-y)Fe2O4 nanoparticles, and to enhance their specific surface area saturation magnetization, the optimization involved adjusting element proportion, calcination temperature, solvent amount. The optimal proportion of x:y:(1-x-y) nanoparticles 0.1:0.7:0.2, effects amount, temperature were also investigated. average particle size Co0.1Mg0.7Cu0.2Fe2O4 calcined at 400 °C with 25 mL absolute alcohol 17.9 nm 56.96 m2/g, respectively; while demonstrating a magnetization 8.5 emu/g. To solve increasingly severe issue water pollution, these employed efficiently treat dye wastewater containing methyl blue (MB). After fitting kinetic isotherm models, adsorption MB dominated by chemisorption multilayer process. experiments revealed remarkable maximum capacity blue, reaching 2255.7 mg/g, within concentration range from 4000 mg/L. thermodynamic analysis indicated spontaneity exothermic studies on effect pH led satisfying results; residual could still remain 91.2% initial adsorbance after 12 times recycle. outstanding recycling ability, resistance ionic strength, distinguished among vast adsorbents. These results highlight significant potential treating wastewater.

In order to solve the shortcomings of a single flocculant, inorganic–organic hybrid flocculant SiO2–CTS–DMDACC was successfully prepared by grafting copolymerization chitosan (CTS), dimethyl diallyl ammonium chloride (DMDACC), and silicon dioxide (SiO2). The performance in treating papermaking wastewater investigated, mechanism flocculation process analyzed. results showed that crystallinity reduced due introduction DMDACC SiO2. water solubility thermal stability with rough porous structure were enhanced. enhanced cationic properties CTS–DMDACC compared CTS. addition, CTS–DMDACC, SiO2 increased viscosity SiO2–CTS–DMDACC. experimental treatment effect CTS:SiO2:DMDACC 1:2:4 best better than CTS at pH 7 for wastewater. removal rates turbidity, COD, NH4+-N 99.43%, 82.92%, 78.43%, respectively. revealed charge neutralization main SiO2–CTS–DMDACC, adsorption bridging net sweeping played supplementary roles
