Abstract

The invention relates to uranium adsorption for uranium-containing wastewater, in particular to an adsorbent for removing low-concentration uranium and application thereof. The adsorbent is obtained by drying and smashing plant leaves, modifying the plant leaves by a diethylenetriamine-isopropanol mixed solution and washing and drying a product. The adsorbent is applied to adsorb uranium in the uranium-containing wastewater at the pH value of 8.2 and is higher in adsorption efficiency.

Description

technical field

[0001] The invention relates to uranium adsorption of uranium-containing wastewater, in particular to an adsorbent for removing low-concentration uranium and its application. Background technique

[0002] As an economical and clean energy, nuclear energy can effectively alleviate the pressure of energy shortage. As the main raw material of nuclear energy, uranium can be used as fuel in nuclear reactors to convert nuclear energy into electrical energy. At present, the production capacity of natural uranium in China can only meet 1 / 3 of the demand, and the supply of uranium is under great pressure. A large amount of low-concentration uranium-containing radioactive wastewater is produced in the production process of uranium mining and metallurgy, which poses a serious threat to the ecological environment and human health. How to effectively control and recover uranium in wastewater has become an urgent problem to be solved.
