Abstract

The invention discloses a method for simultaneously measuring five corrosion removers in leather by adopting ultraperformance convergence chromatography, and belongs to the technical field of chemicalanalysis detection. The method comprises the steps of building a convergence chromatography technical program applicable to simultaneously detecting five corrosion removers including N-octyl isothiazolone, 2-(thiocyanic methyl sulfydryl)benzothiazole, 4-chloro-3-cresol, triclosan and o-phenylphenol in leather, a target compound is extracted, concentrated and filtered, qualitative and quantitativeanalysis is performed through the ultraperformance convergence chromatography, and the method is applicable to simultaneously measuring the five corrosion removers in leather shoes, leather productsand other leatherware. The method is high in sensitivity, good in stability, easy and rapid to operate, low in cost, environmentally friendly, and easy to apply and popularize.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and more specifically relates to a method for simultaneous determination of five preservatives in leather by ultra-high-efficiency convergence chromatography. Background technique [0002] The main function of preservatives is to inhibit the growth and reproduction of microorganisms, to prolong the storage time of consumer products, and to inhibit the corruption of substances. Prohibited preservatives have great biological toxicity to the human body, and can cause various diseases when inhaled or absorbed through the skin. Moreover, they also have an accumulation effect, a long natural degradation process, and are harmful to the environment. [0003] With the continuous development of science and technology, businesses have used a series of new toxic and harmful substances in order to avoid existing regulations. Therefore, it is necessary and urgent to establish and standa...
