Abstract
A radioactive waste acid is recycled. The waste acid is a fluoboric waste acid. The waste acid contains a lot of oxides and radioactive nuclei. The waste fluoboric acid is processed to obtain a purified fluoboric acid. The amount of radioactive nuclei is greatly reduced. Thus, the present invention has a simple procedure with low cost and reduced power consumption.
Claims9
A method of recycling a radioactive waste acid, comprising steps of:
- (a) removing solid objects in a fluoroborate waste acid, wherein said solid objects are oxides and radioactive nuclei;
- (b) adding a sulphuric acid to said fluoroborate waste acid to be reacted to obtain an acidic solution having metal sulphates;
- (c) crystallizing said acidic solution through convection with a cooling water to obtain crystals of said metal sulphates containing crystallization water;
- and
- (d) processing solid-liquid separation to separate crystals of said metal sulphates from said acidic solution.
