An erythrosin B-based “turn on” fluorescent sensor for detecting perfluorooctane sulfonate and perfluorooctanoic acid in environmental water samples

A novel sensing method has been proposed for the highly sensitive detection of PFOS and PFOA in aqueous solution based on the “off-on” switch of erythrosine B (EB)-hexadecyltrimethylammonium bromide (CTAB) system.147
