Autor: A. Z. Zalov, N. A. Verdizade, A. B. Hadjieva
Publikováno v: Pakistan Journal of Analytical & Environmental Chemistry, Vol 16, Iss 1, Pp 16-23 (2015)
The interaction of molybdenum (VI) with o-hydroxythiophenol derivatives (HTPDs) and aromatic amines (AAs) was studied. The following three HTPDs, which contain different halogen atoms at position 5, were used: 2-hydroxy-5-chlorothiophenol(HCTP), 2-hy

EXTRACTION-SPECTROPHOTOMETRIC STUDY ON THE COMPLEX FORMATION IN THE NICKEL (II) - 4-HYDROXY-3-THIOLBENZOIC ACID - DIPHENYLGUANIDINE SYSTEM
Autor: Ali Z. Zalov, Kerim A. Kuliev, Sevil M Shiralieva, Zohra Q Askerova
The conditions for the complexation of nickel (II) with 4-hydroxy-3-thiolbenzoic acid (HTBA) and diphenylguanidine (DPG) are optimized, such as the formation of the complex in time (8 minutes), pH of the medium (pHop 4.2-5.8), the excess of the reage

A mixed-ligand complex of tungsten with 2-hydroxy-5-chlorothiophenol and diphenylguanidine
Autor: A. Z. Zalov
Publikováno v: Journal of Analytical Chemistry. 70:1342-1345
The complexation of tungsten(VI) with 2-hydroxy-5-chlorothiophenol in the presence of diphenylguanidine is studied by spectrophotometry. Optimal conditions for the formation and extraction of the complex are determined. It is found that a mixed-ligan

Extraction-spectrophotometry determination of tungsten with 2-hydroxy-5-chlorothiophenol and hydrophobic amines
Autor: N. A. Verdizade, A. Z. Zalov
Publikováno v: Journal of Analytical Chemistry. 68:212-217
Complexation of tungsten with 2-hydroxy-5-chlorothiophenol (HCTP) and hydrophobic amines (A) was studied by spectrophotometry. Aniline, N-methylaniline, and N,N-dimethylaniline were the examined hydrophobic amines. As was found, in weakly acidic medi
