| Abstract: | In order to determine the different forms of selenium in soil,methods and conditions for the fluorometric determination and extract of different forms of selenium in soil have been studied.The results showed that HNO3-HClO4 is the optimal digestive reagent as digestion of the soil sample,KH2PO4 is the optimal extracts of the available selenium in flooding soil.The fluorometric systematic analytical method of the different form of selenium in soil has been set up.Using the method to determine the different forms of selenium in flooding soil,we can get is satisfying result. |
