Description

Technical Field

[0001] The utility model relates to the technical field of textile detection, in particular to a device using ionic liquid as an extraction medium for extracting alkylphenol polyoxyethylene ether in textile samples. Background Art

[0002] Alkylphenol polyoxyethylene ether (APEO) is a nonionic surfactant widely used in the textile industry. Due to its excellent cleaning, emulsifying and wetting properties, it is often added to various detergents and softeners. However, the persistence of APEO and its degradation products in the environment and their potential endocrine disrupting properties have attracted widespread attention. These substances are difficult to degrade in water and soil, and may pose long-term risks to wildlife and human health.

[0003] Traditional APEO extraction technology mainly relies on organic solvents, such as methanol and dichloromethane, for liquid-liquid extraction. These methods are not only complicated and time-consuming, but also use organic solvents that are harmful to the environment and pose a threat to the health of operators. For example, the use of dichloromethane has been strictly restricted in many countries and regions due to its high volatility and potential carcinogenicity.

[0004] In view of this, it is urgent to develop a new extraction technology that has low environmental impact, high extraction efficiency and good operational safety. Ionic liquids, as a new type of green solvent, have low vapor pressure and good chemical stability, providing a potential solution. Ionic liquids can not only effectively dissolve APEO, but also perform efficient extraction operations without producing volatile organic compounds, significantly reducing the environmental and health risks brought about by the use of traditional organic solvents. Therefore, the present invention aims to provide a device using ionic liquid as an extraction medium, which can reduce operational complexity and environmental hazards while ensuring high extraction efficiency, and meet the requirements of modern environmental protection regulations.
