pb and cd in water samples were determined by cloud point extraction (cpe) with sodiumdiethyldithiocarbamate (ddtc) as the chelating agent and octylphenoxypolyethanl (triton x-114) asthe surfactant prior to flame atomic absorption spectrometry (faas) determination. the main factorsof affecting the extraction and detection processes were optimized. the preconcentration of 10 ml ofstandard soluti...
Flower-like nanostructures of Sb2 - xBixS3(x = 0.4, 1.0) were successfully prepared using both antimony diethyldithiocarbamate [Sb(DDTC)3] and bismuth diethyldithiocarbamate [Bi(DDTC)3] as precursors under solvothermal conditions at 180 °C. The prepared Sb2 - xBixS3 with flower-like 3D architectures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy disper...
A mutant of Escherichia coli, unable to produce manganese- or iron-containing superoxide dismutase (SOD), was found to contain modest levels of an SOD that was judged to be a copper- and zinc-containing SOD on the basis of inhibition by cyanide and inactivation by either H2O2 or diethyldithiocarbamate. Moreover, the diethyldithiocarbamate-inactivated enzyme could be reactivated with Cu(II), and...
Nineteen young human immunodeficiency virus-infected patients were randomized to receive 400 mg of oral diethyldithiocarbamate (DTC) per m2 or placebo weekly for 12 weeks. Changes in blood CD4+ lymphocytes were not significantly different between groups. However, neutrophil, monocyte, and platelet counts consistently decreased during DTC treatment, suggesting DTC-mediated myelosuppression.
