Preparation of Zirconium Phosphate/Carboxymethyl Cellulose Composite Hydrogel for Cu2+ Removal
Zirconium phosphate (α-ZrP)/carboxymethyl cellulose (CMC) composite hydrogels were prepared through graft copolymerization by the easily scaling-up method. The α-ZrP/CMC hydrogels were characterized through FI-IR, SEM (EDS-SEM), XRD, TGA, BET, swelling and zeta potential measurements. The adsorption of Cu2+ by α-ZrP/CMC hydrogels in aqueous solutions was also studied. The results show that α-ZrP/CMC hydrogels have great adsorption capacity for Cu2+. The analysis results indicated that the adsorption mechanisms of α-ZrP/CMC hydrogel on Cu2+ are mainly through the electrostatic interaction. The adsorption process conforms to the Langmuir model (R2 = 0.9953) and Quasi-second order kinetic model (R2 = 1). Under the experimental conditions explored, the optimal amount of α-ZrP and the DS of CMC are chosen as 0.5 wt% and 1.2, and the adsorption capacity of ZrP-0.5%-CMC-1.2 hydrogel for Cu2+ is 121.21 mg/g. The adsorption isotherms, adsorption kinetics, and thermodynamics studies were also conducted to investigate the adsorption mechanism. Therefore, α-ZrP/CMC hydrogels present excellent adsorption efficiency, shows the potential application in future treatment of Cu2+ wastewater.
期刊介绍:
The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
