✦ Synopsis

Determination of trace vanadium in organic solvents is studied by use of the oxidation of o-dianisidine with t-butyl hydroperoxide. The sensitivity of the catalyzed reaction is optimized by application of a modified simplex method. Under optimum conditions the detection limit is 0.7 ng V I&' in acetonitrile and the relative standard deviation is 0.048. The effect of other metal ions and of co-solvents is discussed. The method is used for trace determinations of vanadium in organic solvents of high purity.

Studies of the electrical conductivities of fractions from the Athabasca bitumen indicate that these materials possess appreciable conducting properties. This can be ascribed, in part, to the network of condensed aromatic systems which occurs in this material and it is possible to co-relate the cond
