The present invention provides an antiviral composition and system for using the same, wherein the antiviral composition includes between about 0.1 to about 0.3 wt % of antimicrobial agent such as benzalkoniumchloride, between about 0.1 to about 1 wt % of chlorinated phenol compound, such as parachlorometaxylenol, between about 0.1 to about 3 wt % of hydrogen peroxide, and at least about 60 wt % aqueous solvent.

The invention belongs to the field of analytical chemistry, and relates to a detection method of chlorinated phenols in a textile through hollow fiber liquid-phase microextraction. The detection method comprises the steps of extracting a sample by using acetone, after concentrating an extracting solution to nearly dry, dissolving by using normal hexane to obtain a solvent, then taking a porous hollow fiber tube as a carrier of microextraction solvent, and transferring all extracted solvent into a high performance liquid chromatograph for subsequent assay determination. The detection method provided by the invention has the advantages that a hollow fiber tube liquid-phase microextraction method is adopted, namely, the hollow fiber tube is taken as the carrier of the microextraction solvent, the extraction, gathering, separation and purification are integrated into a whole, the extraction efficiency is high, the organic solvent consumption is less, the extraction is fast and sensitive, and the like; according to experiment results, the recovery rate and precision of the method both satisfy the demands, and the method can be used for the detection of chlorinated phenol mildew preventives in the textile, and has wide application prospect.
