Calcium Ferrite Nanoparticles: A Simple Synthesis Approach for the Effective Disposal of Congo Red Dye from Aqueous Environments

Inorganics, Journal Year: 2024, Volume and Issue: 12(3), P. 69 - 69

Published: Feb. 24, 2024

Congo red dye is classified as a toxic chemical and can be harmful if ingested, inhaled, or in contact with the skin eyes. It cause irritation, allergic reactions, sensitization some individuals. Thus, this paper, CaFe2O4 nanoparticles were produced by simple Pechini sol-gel approach used an adsorbent material for efficient disposal of from aqueous solutions. The maximum adsorption capacity towards 318.47 mg/g. Furthermore, synthesized exhibit average crystal size 24.34 nm. Scanning electron microscopy (SEM) examination showed that are basically ball-like particles mean grain 540.54 Moreover, transmission (TEM) sample revealed aggregated spherical diameter 27.48 Energy-dispersive X-ray spectroscopy (EDS) pattern reveals composed Ca, Fe, O elements, atomic ratio 1:2:4 these respectively. chemical, spontaneous, exothermic, perfectly aligned pseudo-second-order kinetic model, exhibited excellent conformity Langmuir equilibrium isotherm.

Hydrogels Based on Chitosan and Nanoparticles and Their Suitability for Dyes Adsorption from Aqueous Media: Assessment of the Last-Decade Progresses

Gels, Journal Year: 2024, Volume and Issue: 10(3), P. 211 - 211

Published: March 21, 2024

Water is one of the fundamental resources for existence humans and environment. Throughout time, due to urbanization, expanding population, increased agricultural production, intense industrialization, significant pollution with persistent contaminants has been noted, placing water quality in danger. As a consequence, different procedures various technologies have tested used order ensure that sources are safe use. The adsorption process often considered wastewater treatment its straightforward design, low investment cost, availability, avoidance additional chemicals, lack undesirable byproducts, demonstrated efficacious potential treating eliminating organic contaminants. To accomplish application, need develop innovative materials become an essential goal. In this context, overview recent advances hydrogels based on chitosan nanocomposites their application depollution contaminated dyes reported herein. present review focuses (i) challenges raised by synthesis characterization hydrogels; (ii) discussion impact main parameters affecting process; (iii) understanding isotherms, kinetics, thermodynamic behavior; (iv) examination possibility recycling reusing hydrogels.
