The invention discloses a method for adsorbing uranium in a water solution. An adsorption device used by the adsorption method comprises a liquid preparation system, a pretreatment system, a post column adsorption system, a groove type adsorption system and a waste liquid treatment system; the adsorption device uses a multi-group parallel operation process in of two different modes of adsorption ways; the controllable process on of the adsorption conditions is realized; in addition, the parallel comparison checking screening is can be performed on a plurality of groups of uranium adsorption materials at the same time. The method for adsorbing uranium in the water solution has the advantages that the flow process is simple; the operation is convenient and fast; the system stability is high;the adsorption conditions are controllable; the multi-group parallel comparison experiments can be performed. The checking screening on the uranium adsorption material can be effectively realized; wide application values are realized onfor engineering projects of such as sea water uranium extraction, and uranium waste water treatment and the likeare realized. The problems of shortage of sea wateruranium performance checking and uranium-containing waste water treatment process is lack are solved.
Description
technical field [0001] The invention belongs to the technical field of extracting uranium from seawater, and in particular relates to an adsorption method for uranium in an aqueous solution. Background technique [0002] As global resources dwindle and the population continues to increase, in order to prevent social, political and environmental factors from affecting energy supply security and causing global economic problems, people have begun to explore and utilize unconventional forms of industrial metals and minerals reserves. The main source of uranium is pitchblende U 3 o 8 , the distribution of uranium ore is relatively concentrated, and only 15 countries have economically exploitable uranium ore reserves that can meet the requirements for the development of nuclear power generation, of which Australia and Kazakhstan account for 33%. At the current consumption rate of uranium resources, the global uranium resource reserves can sustain the development of nuclear powe...
