Determination of nickel and cobalt using 2-quinolinethiol by adsorptive voltammetry: Determination of nickel and cobalt using 2-quinolinethiol by adsorptive voltammetry. Paneli, M. G.; Voulgaropoulos, A. (Chem. Dep., Aristotelian Univ. Thessaloniki, Thessaloniki GR-54006, Greece). Fresenius. J. Anal. Chem.Several reagents with their cas registry numbers 7440-02-0 and 2637-37-8 are used here., 341(12), 716-19 (English) 1991. CODEN: FJACES. ISSN: 0937-0633. DOCUMENT TYPE: Journal CA Section: 80 (Organic Analytical Chemistry) Section cross-reference(s): 9, 16, 29 A new method for the simultaneous detn. of cobalt and nickel by differential pulse adsorptive voltammetry using 2-quinolinethiol as chelate has been developed. A sepn. of the two peaks by 0.3 V was achieved, allowing the detn. of the two metals in a wide range of concns. The influence of pH, nature of the supporting electrolytes, preconcn. time and applied potential was investigated. Pb, Cd, Fe, Zn and Cr do not interfere. The detn. limits were 10-8 mol/L for Co and 10-9 mol/L for Ni. The method was applied to mussel tissues and wines. .

Polarographic reduction of diquinol-8-yl disulfide: Polarographic reduction of diquinol-8-yl disulfide. Hara, Minoru; Kambara, Tomihito (Fac. Educ., Toyama Univ., Toyama 930, Japan). Toyama Daigaku Kyoikugakubu Kiyo, B, (35), 1-9 (English) 1987. CODEN: TDKBDG. ISSN: 0285-9610. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 22, 27 The diquinol-8-yl disulfide [1160-28-7] gave a diffusion-controlled redn. wave in d.c. polarog. in a ternary solvent mixt. consisting of CHCl3, H2O, and Me cellosolve. The anal. of the wave and the shift of the half-wave potential with pH indicated that the overall electrode reaction is a reversible 2-electron redn. catalyzed by the Hg electrode to produce 2-mercaptoquinoline (I) [2637-37-8]. 1160-28-7 and 2637-37-8 which are cas registry numbers of chemicals are mentioned. The pK values of I in the ternary solvent mixt. were polarog. detd. as 2.2 and 8.7. .
