METHOD FOR REMOVING INORGANIC SELENIUM IN LIQUID ENVIRONMENT

摘要

A method for removing inorganic selenium in a liquid environment comprises the following steps: (1) determining content of inorganic selenium in a liquid environment, and adjusting the pH value of the liquid environment to 3.0 to 7.0; and (2) adding a reducing agent to reduce the inorganic selenium into an elementary substance of selenium, and separating the elementary substance of selenium from the liquid environment, the reducing agent being selected from a food antioxidant having reducibility. The reducing agent used in the method does not cause pollution to the original liquid environment, and the reaction product is harmless to the human body, so the method is suitable for removing inorganic selenium from liquid foods and food additives containing selenium.
