Stable activable tracers for environmentally significant organic molecules: Stable activable tracers for environmentally significant organic molecules. Ghannam, L. M.; Loveland, W. D.; Baumgartner, D. J. (Dep. Chem., Oregon State Univ., Corvallis, OR, USA). Adv. Identif. Anal. Org. Pollut. Water, Volume 1, 231-8. Edited by: Keith, Lawrence H. Ann Arbor Sci: Ann Arbor, Mich. (English) 1981. CODEN: 53CYAW. DOCUMENT TYPE: Conference CA Section: 4 (Toxicology) Dy tris(dibenzoylmethane) (I) [14837-30-0] and Dy triacetylacetonate (II) [14637-88-8], as potential tracers in biol. systems, were tested for stability and octanol/water partition; in aq. soln. no change in concn. occurred with either compd. and the partition coeffs. were 994 for I and 19.77 for II. The bioconcn. of I and II in the oyster, Ostrea edulis, was similar to published data for environmentally significant compds. (e.g. DDT, toxaphene) and thus, I and II may serve as acceptible tracers for these and similar compds. in biol. systems.

Recognition of metal complex guests: supramolecular extraction of water-soluble lanthanide complexes by biological lasalocid ionophore: Recognition of metal complex guests: supramolecular extraction of water-soluble lanthanide complexes by biological lasalocid ionophore. Tsukube, Hiroshi; Takeishi, Hideyo; Yoshida, Zenko (Department of Chemistry, Faculty of Science, Osaka City University, Sugimoto, Sumiyoshi-ku, Osaka 558, Japan).Several substances are used for example 14637-88-8 and 14553-08-3 which are their cas registry numbers. Inorganica Chimica Acta, 251(1-2), 1-3 (English) 1996 Elsevier. CODEN: ICHAA3. ISSN: 0020-1693. DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Naturally occurring lasalocid ionophore was 1st demonstrated to ext. water-sol. lanthanide tris(acetylacetonates) via inner-sphere complexation into CCl4. This offered higher extn. abilities for small Er3+ and Dy3+ complexes than for large Pr3+ and La3+ complexes. Since the lasalocid extd. lanthanide cations themselves nonselectively, this metal complex recognition has new and interesting possibilities in sepn. and sensing of valuable lanthanides. .
