Arsenic is to be found in different oxidation states and it can form various species, most often AsIII which is carcinogenic. Total arsenic content can be determined mostly by methods of atomic spectrometry. In order to determine the concentration of each specie separately, especially the content of carcinogenic AsIII, one needs to separate it from other species before the analysis. Specie-based analysis consist, in general, of two steps: firstly, separation via various forms of arsenic and secondly, their quantification. Cloud point extraction (CPE) was proven to be a suitable technique for this task since it is accurate, effective, safe, and neither time nor money consuming. CPE extraction uses low amounts of organic solvents, thus being environmentally-friendly. The combination of such a separation method with the detecting techniques - such as atomic absorption spectrometry with electrothermal atomisation, or atomic absorption spectrometry with the hydride generation, atomic fluorescent spectrometry with the hydride generation, or UV-VIS spectrometry - may be the key to detecting various forms of arsenic. It is possible to create an easy, highly sensitive, and eco-based methodology which is to be used to determine trace content of arsenic in any environmental samples, food products, or biological samples.
