Published: Feb. 10, 2024

As a result of rapid urbanization and the luxurious lifestyle overgrowing population this planet, currently, consumers are tremendously dependent upon various types industrial productions to maintain their daily life demands. Therefore hasty fluctuating technologies bulky production create colossal amount wastewater every moment which is usually loaded with hazardous toxicants that could not only damage ecology but also hamper public health safety very harshly. Thus, sustainable eco-friendly cost-effective technique crucial need for effective removal these from real-time protect environmental pollution. Whereas continuous mode adsorption by fixed bed column has widely been considered as most simple, cost-effective, ecofriendly technique. Lately, activated chitosan-modified natural clay based nanocomposites have frequently developed due greater availability, easiness fabrication, effectiveness, efficiency biodegradability multifunctional bionanocomposites/adsorbents. Additionally, specific new class biopolymeric exhibits sensational knock regarding performance aqueous solutions around∼99%. However, review article recapitulates noteworthy information about potential fabrication routes characterization techniques chitosan-clay bionanocomposites. Also against immerging bulk scale significant accepted method namely adsorption. A squat overview chemical activation waste biomass shell-derived chitosan modification clay, along interaction during compounding. The possible mechanism elimination contaminants including all chemisorption, multi/monolayer physisorption interparticular diffusion mathematical modellings presented. Future research route suggested technological challenges commonly come across in enactment.

Ball–milled TiO2/biochar hybrid system as a heterogeneous photocatalyst for tannery dyes removal in aqueous solution

Journal of Molecular Liquids, Journal Year: 2024, Volume and Issue: 399, P. 124357 - 124357

Published: March 6, 2024

TiO2/biochar (C/TiO2)BM hybrid photocatalytic system is prepared, for the first time, by a cost-effective method (ball-milling procedure) and used removal of two organic dyes, labeled as Acid Blue 7 Red RTN, employed in tanning industry. The physicochemical properties are investigated different characterization methods, evidencing presence TiO2 anatase phase composite. performance evaluated degradation RTN UV light irradiation. results show similar efficiency (about 70 %) both dyes under at spontaneous pH solution (pH = 6). On other hand, tests acidic conditions 2) indicate higher adsorptive composite with an overall 86 95 %, respectively. Finally, reused up to five cycles without loss performances, underlining stability Therefore, could be effective, recyclable, stable material removing tannery from aqueous solutions adsorption/photocatalysis.
