| titleOfInvention | Method for extracting micro-plastic |
| abstract | The invention provides a method for extracting micro-plastic, which takes the micro-plastic in facial cleanser as a target to separate pollutants, the facial cleanser is dispersed in a salt solution, the micro-plastic floats on an upper layer, after a lower layer solution is discarded, an organic solvent is used for defoaming an upper layer liquid containing the plastic, the micro-plastic is precipitated on a lower layer, after the upper layer solution is discarded, the extracted micro-plastic is washed, vacuum filtered and dried, and finally the dried micro-plastic is obtained. The extraction method provided by the invention can efficiently eliminate colloid and foam in the facial cleanser, does not affect the physicochemical characteristics of the micro-plastics, solves the problems of long time consumption, low efficiency, filter membrane blockage caused by colloid and the like in the extraction process in the prior art, avoids using an organic solvent with high toxicity, ensures the health of experimenters, is economic and environment-friendly, and provides a new method for separating micro-plastic pollutants in the facial cleanser. |
