With the develo pment of industrialization, the waste water containing heavy metal ions has produced more and more. Heavy metal has become one of the most important, the most common contaminants. Due to heavy metals in organisms enrichment, absorption and transformation, which is harmful to human health through the food chain. Such as carcinogenic, teratogenic, so heavy metals monitoring plays a crucial role in environmental protection.This paper introduces in detail the pretreatment method of heavy metal in the monitoring process, in order to better provide the basis for monitoring and treatment of heavy metals in water.
