Flotability, selectivity and flotation separation of plastics by using a surfactant

• In this paper, the floatability of seven plastics (POM, PVC, PET, PMMA, PC, PS and ABS) in the presence of alkyl ethoxylated nonionic surfactant (15-S-7) was investigated. It was found that the floatability of all the plastics decreases with the addition of the surfactant; but they are different in floatability and follow the order POM
