Effect of cupric ions on the analysis of ethylenebis(dithiocarbamate) residues in tomato juice.
Cupric ions interfered with the carbon disulfide evolution assay method for dithiocarbamate residues in tomato juice and in aqueous solution. Amounts of residue determined were reduced when CuSO4 and a formulation of copper fungicide (Copper-Count-N) were present in the solutions analyzed.
