Tóm tắt

Selenium (Se) is an essential trace element that is toxic to humans in a relatively small excess. In natural waters it occurs mainly in inorganic form as Se(IV) and Se(VI) oxyanions with the former being more toxic at high levels. With the increasing use of advanced oxidation processes in drinking water treatment, the oxidation of Se(IV) with unactivated peroxymonosulfate (PMS) has been investigated, but the role of bromide (Br
