The occurrence of sulfonamide antibiotics (SAs) in estuarine waters urges insights into their environmental fate for ecological risk assessment. Although many studies focused on the photochemical behavior of SAs, yet the effects of halide ions relevant to estuarine and marine environments on their photodegradation have been poorly understood. Here, we investigated the effects of halide ions on the...
A new method was developed for the simultaneous speciation of inorganic selenium and antimony in water by electrothermal vaporization inductively coupled plasma mass spectrometry (ETV-ICP-MS) following selective cloud point extraction (CPE). The method is based on the fact that Se(IV) and Sb(III) could form complexes with diethyldithiocarbamate (DDTC) at pH 6.00, and the complexes were quantitatively...
