    Methylated antimony(V) compounds: Synthesis, hydride generation properties and implications for aquatic speciation (1992)

    Notizen: Reports in the literature that the compounds MeSb(O)(OH)2 and Me2Sb(O)(OH) are present in marine and fresh-waters need to be re-examined. The results of several synthetic strategies suggest that these methylantimony(V) compounds are either environmentally inaccessible or polymeric in nature. Pure samples of various di- and tri- methylated antimony(V) species were prepared and found to undergo molecular rearrangement reactions when subjected to hydride generation procedures typically used for aquatic speciation.

    The photo-oxidation of solutions of arsenicals to arsenate: A convenient analytical procedure (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Applied Organometallic Chemistry 2 (1988), S. 1-7

    Thema: Chemie und Pharmazie
    Notizen: The separation of arylarsonic acids by HPLC on a reverse-phase C18 column is described. Solutions containing these arsenicals and others such as arsenobetaine are photo-oxidized to arsenate by ultraviolet (UV) radiation (1200 W, 1 h exposure). This allows the analysis of the solution for arsenic by hydride generation techniques. The method, UV HGAA, is developed and applied to the determination of arsenic in the methanol extracts of the Manila clam (Verupis japonica) and the Horse clam (Schizothoerus nutalli).
