| Abstract: | Seleniumforms are related to its function and toxicity, to choose the appropriate preprocessing is the precondition of seleniumspeciation analysis accuracy due to the complexity of environmental samples in the morphological analysis.The pretreatment methods in seleniumspeciation analysis mainly include the liquid phase extraction,microw ave assisted extraction,solid phase microextraction and liquid phase microextraction. This paper simply analyses the principles and characteristics of every pretreatment method, applications of all pretreatmentand morphologicalmethods,theiradvantagesand disadvantages,and prospectsthe application ofelementspeciation analysis. |
