Development of spectrophotometric determination of beryllium in beryl minerals using chrome Azurol S

Hisham K. Fouad, +2 more
- 01 Sep 2016 - 
TL;DR: In this paper, a 1:1 Be-CAS complex was formed instantly with duration time of at least 24h with constant absorbance, without either solvent extraction or ion exchange separation of beryllium from its matrix.
Journal ArticleDOI

Rapid derivative spectrophotometric method for the determination of platinum in Pt-Ru/C catalyst using iodide media.

Maria Balcerzak, +1 more
- 05 Mar 2001 - 
TL;DR: Platinum was selectively determined by numerical calculation of the 4th-order-derivative absorption spectrum of the mixture of iodide complexes of both metals by the use of derivative spectrophotometry.

Complexation with calixarenes and efficient supercritical CO2 extraction of Pb(II) from acidic medium

Nilesh V. Rathod, +4 more
- 14 Oct 2014 - 
TL;DR: In this paper, the authors describe the extraction of lead(II) from acidic medium with supercritical carbon dioxide using various calixarenes, which involves the investigation of the effect of temperature, acid molarity, and the metal to complexing agent molar ratio on supercritical fluid extraction efficiency.

Uranium removal from aqueous medium using Co 0.5 Mn 0.5 Fe 2 O 4 nanoparticles

Mahmoud O. Abd El-Magied, +5 more
- 01 Feb 2021 - 
TL;DR: In this article, Co0.5Mn 0.5Fe2O4 nanoparticles were successfully synthesized for uranium removal from aquatic media, and the results showed that the Co0Mn0.4 is an effective adsorbent with a higher affinity toward the removal of uranium ions, adsorption capacities of 104mg/g.
