Anwendung

N,N-Dimethyl-1,4-phenylenediamine oxalate (N,N-dimethyl-p-phenylenediamine hemioxalate salt, DPD) was used as reagent in a study to evaluate the catalytic effects of elemental sulfur nanoparticles on CrVI reduction. It was also used to study the transformation of trichloroethene (TCE), caused by heating contaminated soil and groundwater samples.

Chromate (CrVI) reduction by sulfide was conducted in anaerobic batch experimental systems. The molar ratio of the reduced CrVI to the oxidized S(-II) was 1:1.5 during the reaction, suggesting that the product of sulfide oxidation was elemental sulfur. Under the

Klebsiella pneumoniae RS-13 and Acetobacter liquefaciens S-1, both methyl red (MR)-degrading bacterial strains, degraded N,N'-dimethyl-p-phenylenediamine (DMPD) under aerobic conditions. DMPD, a toxic and mutagenic aromatic amine, is formed during the reductive cleavage of azo dyes such as MR. The effects

N,N-Dimethyl-p-phenylenediamine (DMPD) reacted directly with oxyhemoglobin under formation of ferrihemoglobin and, presumably, the N,N-dimethyl-p-phenylenediamine radical cation (DMPP.+). The apparent second-order rate constant of this reaction was 1 M-1 s-1 (pH 7.4, 37 degrees C). The reaction rate was diminished by
