of K-pyrrolidine-1-carbodithoinat was successfully
applied for the spectrophotometric determination
of trace amounts of Cu [14]. The authors
discuss producing thiuram disulphide in the solution
by oxidising of the reagent mentioned by
adding iodine.
In the present study Na-DTC is used both as a
complex forming agent and as a collector. This is
the main advantage of the proposed approach.
The co-precipitation runs according to the following
scheme:
