چکیده
Ecofriendly adsorbent materials for the rapid and efficient removal of pollutant dyes are highly desired on account concerns about environmental pollution human health. Herein, novel magnetic HC/Fe3O4 spherical have been constructed via crosslinking hydroxyethyl cellulose (HC) by poly(ethylene glycol) diglycidyl ether (PGDE) followed introduction Fe3O4 a facile effective strategy developed in this work. The morphology, structure behavior, point zero-charge (pHzpc) Brunauer-Emmet-Teller (BET) systematically investigated. Further, were utilized to remove congo red (CR-SO3Na) from aqueous solution under varying adsorption conditions. Meanwhile, kinetics, thermodynamics isothermics achieved explore process possible mechanism CR-SO3Na materials. show not only an capacity solution, but also sufficient property recovery after adsorption. great potential be used as adsorbents dye-containing effluent.

Functionalization of Microcrystalline Cellulose with N,N-dimethyldodecylamine for the Removal of Congo Red Dye from an Aqueous Solution
Microcrystalline cellulose (MCC) was functionalized with quaternary amine groups for use as an adsorbent to remove Congo Red dye (CR) from aqueous solution. The ultrasonic pretreatment of MCC was investigated during its functionalization. Characterization was conducted using infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and scanning electron mic...
متن کاملRemoval of Congo red from aqueous solutions using nano-Chitosan
It is now recognized that adsorption using low-cost adsorbents is an effective and economic method for water decontamination. Chitosan is derived by deacetylation of the naturally occurring biopolymer chitin which is the second most abundant polysaccharide in the world after cellulose. In this study, the capacity of the chitosan nanoparticles was studied for the removal of the anionic Congo red...
متن کاملSynthesis of nickel hierarchical structures and evaluation on their magnetic properties and Congo red removal ability.
Novel nickel hierarchical structures were prepared through a facile one-pot solvothermal approach in the presence of surfactant and mineralizer. The influence of dynamics factors such as polyvinylpyrrolidone (PVP) content, ratio (R) between NaF and NH(3)·H(2)O on the morphologies of the as-synthesized products were investigated in detail. By regulating the dynamics factors, nickel crystals with...
متن کاملFast removal and recovery of congo red by modified iron oxide magnetic nanoparticles
The adsorption and removal of congo red from an aqueous solution by iron oxide nanoparticles (IONPs) coated with cetyltrimethylammonium bromide (CTAB) as adsorbent was reported. The novel magnetic separation was quite efficient for the adsorption and desorption of congo red. The effect of temperature, pH of aqueous medium, and interfering ions on the recovery process were also investigated. The...
