| titleOfInvention | A kind of solid-phase microextraction film and its preparation method and application |
| abstract | The invention provides a solid-phase microextraction film, which is composed of polystyrene/divinylbenzene polymer microspheres and polydimethylsiloxane copper mesh coated on the surface. Among them, the copper mesh is used as the support structure, and its surface is coated with polystyrene/divinylbenzene polymer microspheres and polydimethylsiloxane. The solid-phase microextraction film has a large specific surface area, good adsorption performance and high sensitivity, and is more suitable for low-concentration drug-polluted water bodies. The invention also provides a method for detecting drugs in water by using the solid-phase microextraction film. The experimental results show that when the pH of the water sample is 10 and no salt is added, the extraction performance of the solid-phase microextraction film is the best, and the detection limits of ketamine, methamphetamine, and methadrax are 2.0ng/L and 19ng/L, respectively. /L, 1.1ng/L, the limit of quantitation is 6.8ng/L, 62ng/L, 3.5ng/L, respectively. |
