Effects of microplastics on wastewater and sewage sludge ...

15/2/2020, · ZnCl 2, NaI and CaCl 2 can be used to extract microplastics from sludge. They all rely on density-based extraction techniques, which use density differences between sludge and microplastics to separate them. When sludge samples are placed in high density salt solution, plastic particles tend to float to the surface of the solution, while denser sludge materials remain at the bottom of the ...
