Abstract Methylsiothiazolinone (MIT) is a wide spectrum biocide used in different industrial fields. In this paper, the electrochemical behaviour of MIT on gold electrode has been studied and square wave voltammetric methods have been developed to determine this compound at different concentration levels. MIT exhibited and irreversible and diffusion- controlled oxidation process with potential and peak current values pH dependent. This biocide can be determined by square-wave voltammetry (SWV) with a linear response up to 53 mg L−1. Using an adsorptive stripping approach prior to the square-wave voltammetry (SWAdSV) it is possible to analyse samples containing very low concentrations of MIT, with a limit of detection of 0.0080 mg L−1. Both SWV and SWAdSV methods were applied with successful results to determine MIT in different water samples.

水中甲基异噻唑啉酮的测定。金电极电化学行为综合研究及方波伏安法优化

摘要 甲基异噻唑啉酮(MIT)是一种广谱杀菌剂,用于不同的工业领域。在本文中,研究了 MIT 在金电极上的电化学行为,并开发了方波伏安法来测定不同浓度水平的这种化合物。MIT 表现出不可逆和扩散控制的氧化过程,其电位和峰值电流值取决于 pH 值。这种杀菌剂可以通过方波伏安法 (SWV) 测定,线性响应高达 53 mg L-1。在方波伏安法 (SWAdSV) 之前使用吸附剥离方法,可以分析含有极低 MIT 浓度的样品,检测限为 0.0080 mg L-1。SWV 和 SWAdSV 方法均成功应用于测定不同水样中的 MIT。
