The application discloses a kind of
solid beverage granules in the extraction method of microplastic, comprising: S1, to the
solid beverage granules containing microplastic, add alkaline solution,
shake up, then water bath heating, during water bath heating, intermittently add
hydrogen peroxide solution, the addition frequency of
hydrogen peroxide solution is 0.5mL / 10min;S2, after water bath heating is completed, reduce water bath temperature reaction, after reaction is completed, hot suction
filtration and using surfactant flush, suction
filtration obtains microplastic, extraction is completed.The application can be directed to animal and vegetable fat,
protein and
cellulose in the composition of
solid beverage granules are digested, solve the problem that many steps in prior art, time-consuming, solid beverage granules
digestion efficiency is low and prone to cause microplastic loss, improve microplastic extraction accuracy, to realize quantitative detection and research to microplastic in solid beverage granules.
