Fenton Treatment For Flotation Separation Of Polyvinyl

Fenton treatment for flotation separation of polyvinyl ...

31/10/2017  After Fenton treatment under optimum conditions, floatation separation of PVC from plastic mixtures was accomplished with high purity and recovery. The purity and the recovery of PVC are up to 99.26% and 100% respectively. The purity and the recovery of other plastics are up to 100% and 97.20% respectively. Consequently, flotation combined with Fenton treatment is a simple,

Surface treatment with Fenton for separation of ...

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 ...

Fenton oxidation was found to induce selective surface hydrophilization of polymethyl methacrylate and suppress its flotation recovery in flotation, thereby facilitating its flotation separation with polyvinyl chloride. The surface hydrophilization occurred on polymethyl methacrylate surface was confirmed by the contact angle that decreased from 95.80° to 73.11°, and was attributed to the ...

The mechanism of surface treatment shows that oxygencontaining groups are introduced into ABS surface, enhancing the hydrophilicity of ABS, but PVC is almost unaffected and remains floating in flotation process. This study established a novel surface modification with RSM optimization and reliable mechanisms for the flotation separation of waste PVC and ABS. (C) 2020 Elsevier Ltd. All rights ...

Fenton and floatation would be an excellent method to remove solids and chemicals from flow-back water. Furthermore, the percentage of saved water from water flooding processes and chemical enhanced oil recovery methods is approximately 70% and 75%, respectively. Therefore, it only needs 30% and 25% of freshwater to continue water flooding processes and chemical en ...
