Trichlorfon has the capacity to catalyze the oxidation of benzidine (4,4′-diamino-biphenyl) to 4-amino-4′-nitro biphenyl in the presence of sodium perborate. The product of the catalyzed reaction was validated by LC–MS method. Reversed-phase high performance liquid chromatography with 365nm UV detection was used for separation and quantification of 4-amino-4′-nitro biphenyl. It can be proven there...
Based on the formation of tetramethylthiuram disulfide (thiram)-copper(II) complex by square-wave voltammetry on a glassy carbon electrode, a new method is proposed for determination of thiram. There is a good linear relationship between peak current and concentration of thiram in the range of 6.0x10 -6 to8.0x10 -5 moll -1 (r=0.999). The method is applied to...
