Effects of zinc, nickel and copper powders, which were placed on the top of gas-chromatographic column, on the elution of zincOn-, nickel(II)- and copper(II)-dialkyldithiocarbamate [M(drdtc)2] and thiuram sulfides ((R2NCS2)2, (R2NCS)2S) were investigated. It was revealed that the influence of metal powder was intense in the order of copper>nickel>zinc. For example, on zinc powder, [Cu(drdtc)2] and some parts of thiuram sulfides changed to [Zn-(drdtc)2], but no changes were recognized in [Ni(drdtc)2]. On nickel powder, [Cu(drdtc)2], [Zn(drdtc)2] and thiuram sulfides changed to [Ni(drdtc)2]. On the other hand, on copper powder, [M(drdtc)2] and thiuram sulfides were adsorbed on copper powder and did not elute. The adsorbates on copper powder were extracted with N, N-dimethylformamide, DMF, analysed spectrophotometrically and identified as [Cu(drdtc)2]. From the results, it may be deduced that in the presence of metal powder, M', a part of thiuram sulfides formed [M'(drdtc)2], and [M(drdtc)2] is exchanged to [M'(drdtc)2] at the temperature of gas chromatograph.
