Abstract:A sodion triethylenetetramine-bisdithiocarbamate(DTC-TETA) and its complexes with heavy metal ions were investigated by FTIR, UV, FAAS and elemental analysis, respectively. The FTIR spectrum of DTC-TETA showed strong absorption peaks at 1 461-1 388 cm-1 and 1 174-996 cm-1 which were attributed to partly double bonds of CN and CS, respectively. The UV spectrum of DTC-TETA had two absorption peaks at 265 and 290 nm, assigned to π—π* transition of N…C…S radical and nonbonding electron n—π* transition of S…C…S radical to conjugated system, respectively. The elemental analysis results demonstrated that the mol ratio of C, H, N and S in DTC-TETA was about 2∶4∶1∶1. As for UV spectrum of its complexes with Cu(Ⅱ), Cd(Ⅱ), Zn(Ⅱ) and Ni(Ⅱ), there were four new absorption peaks at 321, 310, 311 and 325 nm, respectively. Coupled to flow-injection, FAAS determination showed that the complexation performance of Cu2+,Cd2+,Ni2+ and Zn2+ complexes of DTC-TETA was better than that of sodium diethyldithiocarbamate (DDTC).
