New SPE Sorbent for the Rapid and Sensitive Quantification of Aluminium in Food, Soil Extracts and Water Samples

Alaa S. Amin & Mohammed A. Kassem · International Research Journal of Pure and Applied Chemistry · 2011

An on-line solid-phase extraction (SPE) technique, linked to spectrophotometry, has been developed to overcome the problem of high matrix concentration, which is thought to interfere with the determination of low levels of aluminum in environmental samples. Aurintricarboxylic aci...

Removal of Malachite Green Dye from Aqueous Solutions by an Efficient Nanosized NiO Fabricated by a Facile Sol-Gel Autocombustion

Hesham H. El-Feky, Reham N. Nassar, Alaa S. Amin & Mostafa Y. Nassar · Asian Journal of Chemical Sciences · 2021

Nickel oxide nanostructures were synthesized via a sol-gel combustion method using glucose, glycine and tartaric acid fuels. The effect of the fuel type on the formed nanostructures was studied. The as-prepared products were characterized by means of FE-SEM, HR-TEM, XRD, and FT-I...

Nanoscale Zero-valent Silver and Graphene Oxide Nanoparticles: Facile Synthesis and Characterization

Nouran Yousri, Hesham H. El-Feky, Mostafa Y. Nassar & Alaa S. Amin · Asian Journal of Chemical Sciences · 2024

We herein report a direct and facile hydrothermal method for the preparation of zero-valent silver nanoparticles using a mixture of ascorbic acid/starch as a reducing agent. The average crystallite size of the prepared Ag0 nanoparticles was ca. 46.7 nm. The zero-valent silver nan...
