Batch kinetic studies of adsorption of Cu(II) ions from aqueous solutions onto alginate nanoparticles/PEG binary blend
Among the most prevalent natural biopolymers is alginate. The current effort focuses on creating the binary blend of Alg-Nps/PEG. PEG is a great option because of its many distinctive qualities. Blends of polymers mix the characteristics of the separate polymers. FTIR results show intermolecular hydrogen bonding between Alg-Nps/PEG binary blend. Morphological and cross-sectional studies were analyzed using SEM. Various parameters impacting the Cu(II) ion adsorption, including pH, contact time, and adsorbent concentrations, have been examined in a batch adsorption method utilizing an Alg-Nps/PEG binary blend. Pseudo-first order, pseudo-second order, and intra particle Weber-Morris diffusion parameters have been determined. The experimental data fit the pseudo-second order kinetics model quite well when compared to the pseudo first order and intra-particular diffusion models.
期刊介绍：
Started in 1972, this multi-disciplinary journal publishes full papers and short communications. The Indian Journal of Geo-Marine Sciences, issued monthly, is devoted to the publication of communications relating to various facets of research in (i) Marine sciences including marine engineering and marine pollution; (ii) Climate change & (iii) Geosciences i.e. geology, geography and geophysics. IJMS is a multidisciplinary journal in marine sciences and geosciences. Therefore, research and review papers and book reviews of general significance to marine sciences and geosciences which are written clearly and well organized will be given preference.
