Abstract:
The results of the construction and testing of a data collection system for use with a voltammetric analysis instrument is presented. A solution of copper(II) was studied with the instrument. A miniature electrode with a O.5mm diameter graphite probe made from commercially available mechanical pencil refills was devised. Also, two heteropolytungstates, ([H2OBCo(III)W11O39]•XH2O)-6 and ([prySiCo(III)W11O39]•XH2O)-6 were examined in the presence of 2-propanol. The 2-propanol was found to have little effect on the tungstates in the presence of the graphite electrode.
