摘要：
A novel analytical technique for the determination of tetramethylthiuram disulfide (TMTD) was developed. It is based on total oxidation of TMTD with hypobromite. Hypobromite is generated on one segment of interdigitated array. It reacts rapidly and quantitatively with TMTD and unreacted flux of hypobromite is detected on second segment of the interdigitated microelectrode array ODA). Detection is amperometric therefore the potential of the second (detector) segment is fixed at the value corresponding to the limiting current of the opposite reaction to that taking place on the generator segment. Rather low detection limit of this method (7 x 10(-7) mol dm(-3)) allows the analysis of samples with trace content of TMTD. (C) 2001 Elsevier Science B.V. All rights reserved.
