Comparative study: Correlating extraction efficiency of simple diacid chelates for Hg(II), Cd(II), and pb(II) ions with the number of (CH2) units connecting COO− groups
Autor: Amer A. G. Al Abdel Hamid
Publikováno v: Separation Science and Technology. 53:230-242
Four dicarboxylic chelates (MAL, SUC, ADP, and SUP) were employed to explore the effect of (CH2) extension on extraction efficiency of the corresponding dicarboxylates for Hg(II), Cd(II), and pb(II) ions. Binding effectiveness (extraction efficiency)

Comparative study: Correlating extraction efficiency for Hg(II), Cd(II), and Pb(II) metal ions with the chelate stability and total hardness in simple nitrogen donors
Autor: Amer A. G. Al Abdel Hamid
Publikováno v: Separation Science and Technology. 52:1680-1695
Four N-donors (PHDA, ATPH, APHO, and MTAN) containing NH2 were used to extract Hg(II), Cd(II), and Pb(II). Their extraction capacity was determined by measurement of percentage extraction.The chelates extract these metals differently: for example, ef

An infrared spectroscopic based method for mercury(II) detection in aqueous solutions
Autor: Alice E. Bruce, Asela Chandrasoma, Mitchell R. M. Bruce, Carl P. Tripp, Amer A. G. Al Abdel Hamid
Publikováno v: Analytica Chimica Acta. 728:57-63
A new method that uses solid phase extraction (SPE) coupled with FTIR spectroscopy to detect Hg(II) in aqueous samples is described. The technique is envisioned for on-site, field evaluation rather than lab-based techniques. This paper presents the "

Properties of 2-, 3-, and 4-acetylpyridine substituted ruthenium(II) bis(bipyridine) complexes: substituent effect on the electronic structure, spectra, and photochemistry of the complex
Autor: Sofian M. Kanan, Amer A. G. Al Abdel Hamid
Publikováno v: Journal of Coordination Chemistry. 65:420-430
Bis(2,2′-bipyridine) complexes of ruthenium(II) with 2-, 3-, and 4-acetylpyridine derivatives were synthesized and structurally characterized. The effect of changing the location of the pyridine's acetyl substituent was studied experimentally and t
