Abstract

The invention provides a method for measuring isothiazolinone antibacterial finishing agents in textiles, and relates to the field of product quality analysis, and discloses a method for separating and detecting the five isothiazolinone antibacterial finishing agents. The following liquid phase chromatographic conditions are adopted, and according to the liquid phase chromatographic conditions, a chromatographic column is XR-ODS (2.2 microns), the inner diameter is 100 mm*3.0 mm, column temperature is 40 DEG C, column flow speed is 0.4ml / min, a diode array detector is adopted, and detection wavelengths are 277 nm and 283 nm. According to the gradient elution conditions, the volume ratio of methanol to water is 40 to 60 for 0.00 min; the volume ratio of methanol to water is 90 to 10 for 1.90 min; the volume ratio of methanol to water is 90 to 10 for 6.00 min; the volume ratio of methanol to water is 40 to 60 for 6.01 min; 9.00 min. The five isothiazolinone antibacterial finishing agents are separated, a good baseline separation effect can be achieved, and peak types are sharp and symmetric.

Description

technical field

[0001] The invention relates to the field of product quality analysis, in particular to a method for determining isothiazolinone antibacterial finishing agents in textiles. Background technique

[0002] Isothiazolinone compounds are a new type of fungicides, which have the advantages of high efficiency, low toxicity, long duration of drug effect, and environmental safety, and have attracted extensive attention from experts in the fields of biology, medicine, and chemistry. With the wide application of isothiazolinone compounds in marine antifouling, industrial circulating cooling water treatment, industrial product anticorrosion, agricultural sterilization, etc., the environmental behavior and ecotoxicity of isothiazolinone compounds have attracted great attention. become a research hotspot in this field. EU Cosmetics Regulation 1223 / 2009 stipulates that CMI and MI can be used as preservatives in leave-on and rinse-off cosmetics, and the maximum concentratio...
