Unveiling the promise of biosorption for heavy metal removal from water sources

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 319, P. 100523 - 100523

Published: June 12, 2024

Heavy metals represent a significant contributor to water pollution, posing serious environmental and health risks due human activities industrialization. The release of heavy metal contaminants into sources has spurred extensive research wastewater treatment methods, including precipitation, evaporation, ion exchange, membrane processes, electroplating. However, these conventional techniques often prove costly, limited in effectiveness, may inadvertently exacerbate pollution concerns. This review underscores biosorption as highly promising alternative for effectively removing harmful ions from sources. Biosorption, physical technique, capitalizes on mechanisms such surface complexation, leveraging more economical biological materials biosorbents. Microorganisms, encompassing bacteria, fungi, algae, plant products, emerge pivotal agents biosorption, offering sustainable cost-effective approach. There is growing interest harnessing local microbiota aiming mitigate contamination without adverse impacts. Notably, both living deceased fungal biomass have garnered attention adsorbents eliminating solutions. behavior presents numerous advantages, warranting further fully exploit its potential endeavors.

Green adsorbents for water remediation: Removal of Cr(vi) and Ni(ii) using Prosopis glandulosa sawdust and biochar

Green Processing and Synthesis, Journal Year: 2025, Volume and Issue: 14(1)

Published: Jan. 1, 2025

Abstract Potentially toxic elements like Cr +6 and Ni +2 cause severe health hazards. Therefore, the current work was aimed at cleaning water using Prosopis glandulosa raw sawdust (SD) its derived biochar (AC). Both adsorbents were characterized via SEM, FTIR spectroscopy, EDX, TGA applied for effective removal of Ni( ii ) Cr( vi optimum values experimental conditions, mechanism assessed adsorption isotherm kinetic models. The correlation coefficient R 2 confirmed pseudo-second-order kinetics preferred Freundlich model. Maximum iv obtained a pH 4.0, bio-sorbent concentration 0.8 g·L −1 , temperature 50°C 50 min with metal 110 ppm, while maximum contact time 70 130 ppm in above-mentioned conditions. results isotherms model revealed that processes involved multilayer formation on biosorbent’s heterogeneous surface. Also, their thermodynamic investigation showed process is spontaneous exothermic and, therefore, can be effectively utilized to remove from water.
