The determination of arsenic species is of great importance for human health, but it is still a challenge for analytical chemistry. Complete characterization of arsenic compounds is necessary due to different toxicological effects demonstrated by particular arsenic species. Modern analytical procedures include mainly usage of microextraction techniques which tend to reduce solvent consumption, e.g. liquid phase microextraction (LPME), or employ solvent free methods, e.g. solid phase microextraction (SPME). SPME development focuses on synthesis of new sorbents and application of on-line sample preparation while in LPME usage of new solvents is studied. Among these solvents mainly ionic liquids were applied in LPME, mostly in different dispersive liquid-liquid microextraction procedures but also in hollow fibre liquid phase microextraction. As the ionic liquids are not always environmentally friendly other solvents were also proposed but only limited number of papers were devoted to usage of deep eutectic solvents or surfactants.

砷种类的测定对人类健康非常重要，但对于分析化学仍然是一个挑战。由于特定砷物种表现出不同的毒理作用，因此必须对砷化合物进行全面表征。现代的分析程序主要包括使用微萃取技术，例如液相微萃取（LPME），以减少溶剂消耗，或采用无溶剂方法，例如固相微萃取（SPME）。SPME的开发侧重于新吸附剂的合成和在线样品制备的应用，同时在LPME中研究了新溶剂的使用。在这些溶剂中，主要是离子液体它们被用于LPME中，主要用于不同的分散液-液微萃取程序中，也用于中空纤维液相微萃取中。由于离子液体并不总是对环境友好的，因此还提出了其他溶剂，但是仅有限数量的论文专门用于使用深共晶溶剂或表面活性剂。
