Title: Surface treatment with Fenton for separation of acrylonitrile-butadiene-styrene and polyvinylchloride waste plastics by flotation

Abstract

Highlights: • Surface treatment with Fenton was developed for flotation separation of waste plastics. • Surface treatment changes selectively the floatability of ABS surface. • Mechanism of surface treatment was studied by FT-IR and XPS analysis. • Plastic mixtures with different particle sizes and mass fractions were separated effectively. - Abstract: Surface treatment with Fenton was applied to flotation separation of acrylonitrile-butadienestyrene (ABS) and polyvinylchloride (PVC). After treatment, the floatability of ABS has a dramatic decrease, while the floatability of PVC is not affected. Fourier transform infrared spectroscopy (FT-IR) spectra and X-ray photoelectron spectroscopy (XPS) spectra were recorded to ascertain the mechanism of Fenton treatment. FT-IR and XPS analysis confirms that the introduction of oxygen-containing group occurs on the surface of ABS. The optimum conditions are molar ration (H{sub 2}O{sub 2}:Fe{sup 2+}) 10000, H{sub 2}O{sub 2} concentration 0.4 M/L, pH 5.8, treatment time 2 min and temperature 25 °C, frother concentration 15 mg/L and flotation time 3 min. Particle sizes and mixing ratios were also investigated. Plastic mixtures of ABS and PVC with different particle sizes and mixing ratios can be effectively separated. The purity of ABS and PVC are up to 100% and 99.78%, respectively; the recovery of ABSmore » and PVC are up to 99.89% and 100%, respectively. A practical, environmentally friendly and effective reagent, namely Fenton, was originally applied to surface treatment of ABS and PVC waste plastics for flotation separation of their mixtures.« less
