Preliminarily comparative performance of removing bisphenol-S by ferrate oxidation and ozonation

Abstract Bisphenol-S (BS) has recently raised public concerns for its adverse effect on the health safety and ecological security. BS concentrations were detected in many water resources, ranging from 10 ng L−1 to 300 μg L−1, so that various purification techniques have been sought to remove BS. Thi...
