Simple nanoprecipitation method for size-restricted synthesis of aloevera nanoparticles: Characteristic analysis and its application as an adsorbent

The Nanoprecipitation method has been proved favorable to synthesize size-restricted Aloevera nanoparticles from the aloevera polysaccharide in a very simple and single step. Dropwise addition of 1% homogeneous aloevera solution (1 mL) to absolute alcohol (20 mL) resulted in the formation of 50-100 nm-sized Aloevera nanoparticles. The results showed that the amount of ethanol played a significant role in deciding the shape and size of nanoparticles. The synthesis of aloevera nanoparticles has been confirmed by SEM, FTIR, XRD, and BET studies. The effect of other precipitating mediums and surfactants has also been studied to analyze their effect on the size of nanoparticles. The nanoparticles are also found to be potential adsorbents of Reactive Blue H5G dye which showed an affinity for AVNP and the adsorption study indicated 95% adsorption of the dye in 4 h. This indicates its efficacy as an adsorbent for wastewater treatment.

Automated summary

The Nanoprecipitation method is effective in synthesizing size-restricted Aloevera nanoparticles in a simple and single step. The amount of ethanol used plays a significant role in determining the shape and size of the nanoparticles. The synthesis of the nanoparticles has been confirmed through various tests, and their potential as adsorbents for wastewater treatment has been discovered.
