By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Investigators publish new report on Waste Management Research. According to news reporting originating in Changsha, People's Republic of China, by VerticalNews journalists, research stated, "A new physical method, namely boiling treatment, was developed to aid flotation separation of acrylonitrile-butadiene-styrene (ABS) and polystyrene (PS) plastics. Boiling treatment was shown to be effective in producing a hydrophilic surface on ABS plastic."
The news reporters obtained a quote from the research from Central South University, "Fourier Transform Infrared analysis was conducted to investigate the mechanism of boiling treatment of ABS. Surface rearrangement of polymer may be responsible for surface change of boiling treated ABS, and the selective influence of boiling treatment on the floatability of boiling treated plastics may be attributed to the difference in the molecular mobility of polymer chains. The effects of flotation time, frother concentration and particle size on flotation behavior of simple plastic were investigated. Based on flotation behavior of simple plastic, flotation separation of boiling treatment ABS and PS with different particle sizes was achieved efficiently. The purity of ABS and PS was up to 99.78% and 95.80%, respectively; the recovery of ABS and PS was up to 95.81% and 99.82%, respectively."
According to the news reporters, the research concluded: "Boiling treatment promotes the industrial application of plastics flotation and facilitates plastic recycling."
