This program is, in general, concerned with finding a reaction that is either catalyzed or inhibited by trace concentrations of a metal ion or a metal complex, with which a chemical agent of interest can interfere when present in submicro quantities. Preliminary studies were made of three such systems 1 The effect of ethylenediamine-N,N,N,N-tetraacetic acid EDTA on Mn II -catalyzed oxidation of Malachite Green by periodate 2 the effect of ligands on the Hg II - catalyzed oxidation of arsenic III by cerium IV and 3 the effects of ligands on the Ag 1 - catalyzed oxidation of arsenic III by cerium IV. The preliminary results obtained in each of the systems studied provide sufficient encouragement to justify further exploration. It is expected that practical methods based on the Ce IV - As III system could be developed for sulfur-containing ligands. New systems involving catalysis by metal ions, such as Cu and Fe will be investigated, since with these metals ligands containing nitrogen and oxygen should have significant effects. Author
