A Cd(II) adduct [Cd(DBTC)2(4,4'-bipy)] (2) was synthesized by mixing 4,4'-bipyridyl with the precursor [Cd(DBTC)2]2 (1) (DBTC=N,N-dibenzyl dithiocarbamate anion) and characterized by X-ray crystallography structural analysis and IR spectra respectively.

The chelating properties for heavy metals of modified corn starch which contains dithiocarbamate group(DTCS) have been studied.

Four metal complexes, which were shown as [Cd(DBTC) 2] 2 (1), [Hg(DBTC) 2] (2), [Nd(DBTC) 3·2H 2O] and [Nd(DBTC) 3(HMPA) 2] (3) (where DBTC=N,N-dibenzyl dithiocarbamate, HMPA=hexa~methyl~phos~pho~ra~mide), were synthesized and characterized by IR spectra.

Four kinds of dithiocarbamates were prepared and their mechanisms to remove oil were studied.

The mechanism of removing oil from wastewater by dithiocarbamate was studied and the effect of pH value of wastewater on the oil removing was discussed based on the floculation occurred in the course of oil removing.

A new kind of three-group coordination polymerization agent tri(dithiocarbamate) cyanuric acid(TDC) was designed and synthesized,and the feasibility to use TDC as a kind of coordination polymerization precipitant for heavy ions was investigated.

Removal of copper ions and turbidity by a new kind of three-group coordination polymerization precipitant,tri(dithiocarbamate) cyanuric acid,(TDC) was studied in this paper.

In order to investigate the inhibiting mechanism of sodium dithiocarbamate (DTC) to the corrosion of mild steel in sulfuric acid, a series of dithiocarbamate corrosion inhibitors were synthesized by using amine and CS_2 as the reactants and were then characterized by IR spectra.
