Adsorptive stripping voltammetric measurements of trace levels of uranium following chelation with Mordant Blue 9

Adsorptive stripping voltammetric measurements of trace levels of uranium following chelation with Mordant Blue 9. Wang, Joseph; Zadeii, Javad M. (Dep. Chem.In this study， 3624-68-8 and 7440-61-1 are also used., New Mexico State Univ., Las Cruces, NM 88003, USA). Talanta, 34(2), 247-51 (English) 1987. CODEN: TLNTA2. ISSN: 0039-9140. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) The chelate of U with the azo dye Mordant Blue 9 is shown to be adsorbed and then reduced on the hanging Hg drop electrode. These properties were used in developing a highly sensitive stripping voltammetric procedure for trace detn. of U. With controlled adsorptive accumulation for 5 min, a detection limit near 2 ′ 10-10M U is obtained. Cyclic voltammetry was used to characterize the interfacial and redox behavior. The effect of various operational parameters on the stripping response is discussed. Exptl. conditions include use of 1 ′ 10-6M Mordant Blue 9 in 0.05M acetate buffer (pH 6.5), an accumulation potential of -0.43 V, and a linear potential scan. The response is linear up to 1.2 ′ 10-7M U and the relative std. deviation at 4.2 ′ 10-8M is 3.2%. The effects of possible interferences from org. surfactants or metal ions were investigated. .

Differential inhibition of brain specific [3H]flunitrazepam binding by several types of dyes

Differential inhibition of brain specific [3H]flunitrazepam binding by several types of dyes. Smith, Thomas M.; Squires, Richard F. (Rockland Res. Inst., Orangeburg, NY 10962, USA). Neurochem. Res., 8(9), 1177-83 (English) 1983. CODEN: NEREDZ. ISSN: 0364-3190. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Several dyes, representing different structural classes, inhibit 3H-labeledflunitrazepam [1622-62-4] binding to brain specific receptors in the rat with 50% inhibition in the 1-100 mM range. Crystal Violet (I) [548-62-9] and Methyl violet 2B [8004-87-3] inhibited more potently in the forebrain than in the cerebellum. Congo Red [573-58-0] yielded a Hill no. near 2. 72-57-1 and 3624-68-8 which are cas registry numbers of chemicals are mentioned.3, probably reflecting pos. cooperativity between interacting binding sites in benzodiazepine receptor complexes. Toluidine Blue 0 [92-31-9] was the most potent of the dyes tested (median inhibitory concn. 1 mM in cerebellum) and inhibited more potently in cerebellum than in forebrain. .
