Environmental samples with low concentrations of the measured complex components, interfering substances and environmentally sensitivities, need to be pretreated before analyzed. The importance of sample preparation and three pre-treatment technologies with widely applications and good development are described in this paper. It is very important for environmental sample detection with selecting appropriate sample pretreatment methods, and it is also a key problem of environmental monitoring experiment teaching.
