Abstract:Originally, the application of commercially available monothiohexafluoroacetylacetone (HFAS) and its formation of volatile chelates with metals of environmental significance to rapid, multi-element analysis was under investigation. Inability to reproduce published results for the Nickel chelate led to critical examination of the chelating agent and ultimately to withdrawal of the compound from the commercial market when its identity and purity were found to be questionable. Independent synthesis of HFAS was unsuccessful and initial project objectives were abandoned. Project objectives were redirected to verification and extension of previous studies involving the lead chelate of 2,2,6,6-tetramethylheptane-3,5-dione (PIV) . Extraction studies were conducted using flameless atomization atomic absorption for analysis but are of questionable value as a result of analytical inconsistencies. Gas chromatographic studies indicated previously reported synthesis of Pb(PIV)₂ had likely not been achieved. Both HFAS and PIV studies were unsuccessful and have resulted in programs of independent synthesis and continued research at The University of Tennessee where the Principal Investigator is now in residence.
