Presently, hazardous metal and dye removal from wastewater is one of the major areas of research focus. For the elimination of these contaminants, many approaches have been devised and applied. However, the accomplishment of various water treatment processes has largely depended on the medium utilized and the associated problem with the leaching of harmful compounds into the water process with most commercial and chemically manufactured materials for water treatment processes. Hence, this study is aimed at reviewing existing studies on the sorption of heavy metals (HMs) and dyes using bionanocomposites (BNCs). The key focus of this review is on the development of eco-friendly, effective, and appropriate nanoadsorbents that could accomplish superior and enhanced contaminant sequestration using BNCs owing to their biodegradability, biocompatible, environmentally friendly, and not posing as secondary waste to the environment. The sorption of most pollutants was observed to be pH, sorbent dosage, and initial contaminant concentration-dependent, with most contaminants’ elimination taking place in the pH range of 2-10. The sorption process of HMs and dyes to various BNCs was superlatively depicted utilizing the Langmuir (LNR) and Freundlich (FL) as well as the pseudo-second-order (PSO) models, suggestive of the sorption process of a monolayer and multilayer and the chemisorption process, the rate-limiting stage in surface sorption. The established sorption capacities for the reviewed sorption process for various contaminants ranged from 1.47 to 740.97 mg/g. Future prospective for the treatment and remediation of contaminated water using BNCs was also discussed.

“…13 depicts a schematic representation of the above-stated protocols. 152 Li et al prepared magnetic mesoporous silica nanocomposites coated with chitosan. Dye adsorption kinetic and adsorption isotherm analysis were studied using MB as the model dye wherein the prepared nanocomposites exhibited good magnetic response and adsorption capacity; CMMSNs displayed a saturated adsorption capacity of 43.03 mg g À1 for MB.…”

“…195 Kazemi et al concluded that the process of adsorption of MB using magnetic zeolite/chitosan/alginate (MZ/CS/AL) bio-sorbent was found to be an exothermic reaction with negative DH1. 152 CTS-g-PTMAAC/SC-Fe 3 O 4 was used to degrade FY3 and the adsorption was discovered to be spontaneous, exothermic, and entropy-driven. 133 The impact of temperature on the adsorption of DB367 by composites revealed that the adsorption was endothermic and improved with increasing temperature, with the maximum at 363.15 K. The sudden increase in the adsorption capacity at 353.15 K might be because of the dye distribution in the adsorbent's interspace structure which might have been influenced by the enhancement of temperature.…”

“…Because biomass wastes contain a variety of functional groups, including amino, carboxyl, carbonyl, hydroxyl, sulfonic acid, and phosphoric acid, these groups will induce pollutants bound to the walls of biological materials 22 . Zeolite is used not only in the field of water softening, but also in traditional applications of zeolite, and also in wastewater treatment, catalytic processes, antibacterial purposes, membrane separation, construction, coatings, pulp, and paper, plastics, refractories, and ceramics 23 – 26 .…”

A comprehensive study combined experimental, computational and field experiments was conducted to find out the most appropriate adsorbent system for industrial elimination of congo red (CR) dye from simulated industrial wastewater. Modification of the zeolite (Z) by the Padina gymnospora algae (PG) (Egyptian marine algae) was evaluated in terms of the adsorption capability of the zeolite (Z) to remove CR dye from aqueous solutions. The zeolite/algae composite (ZPG) was fabricated using the wet impregnation technique. Various techniques were used to characterize the PG, Z, and the produced ZPG nanocomposite. Batch experiments were performed to study the influence of various practical variables on adsorption processes. The isotherms and kinetics of dye adsorption were also studied. The newly synthesized ZPG nanocomposite exhibits much higher adsorption capacity, especially at low CR concentrations than that of Z. The computational calculations have shown that owing to the presence of intermolecular interactions, the adsorption of the CR molecule on zeolite surfaces is exothermic, energetically favorable, and spontaneous. For all configurations, increasing the zeolite size does not have a noticeable impact on the adsorption energies. The experimental results revealed that the ZPG nanocomposite can be applied as an economical nanoadsorbent to eliminate anionic dyes from simulated industrial wastewater at low CR dye concentrations. The adsorption isotherm of dye onto Z, PG, and ZPG almost agreed with Langmuir isotherm and pseudo-second-order kinetics. The sorption mechanism was also evaluated using Weber's intra-particle diffusion module. Finally, the field experiments revealed optimistic results for the newly synthesized adsorbent in removing dyes from industrial wastewater with 82.1% efficiency, which in turn confirmed the foundation of new eco-friendly materials that aid in the reuse of industrial wastewater.
