Abstract Scope |
The sol-gel process is a wet chemical approach that have been used for generating numerous metal oxide nanoparticles (NPs) due to its cost-effectiveness and superior control over the products chemical composition. NPs achieved using the sol-gel approach can be utilized in several electronic, optical, surface engineering, energy, pharmaceutical, biosensors, separation technologies and adsorption of heavy metals. Several studies have used silica NPs obtained via sol gel strategy in removing heavy metals from their solutions. The remarkable heavy metal adsorption efficiency reported over the years is due to remarkably instinctive features like high surface area, mesoporous structure, tunable pore size/diameter, etc. This review detailed a concise study on Silica NPs synthesized using the Sol gel approach and recent applications in the removal of heavy metals from their solutions. Possible challenges in using silica NPs were also elaborated. |
