Embodiment 1
[0035] (1) Take water as raw material, add selenium and iodine, react under normal pressure, the mol ratio of water, selenium and iodine is: water: selenium: iodine=1:1.3:2.7, and reaction temperature is 28 ℃, and the reaction time is 40min, the complete mark of reaction is no longer producing gas, and the reaction obtains selenous acid solution and hydroiodic acid, and the reaction equation is as follows:
[0036] 3H 2 O+Se+2I 2 →H 2 SeO 3 +4HI
[0037] The hydriodic acid and selenous acid generated above are obviously layered due to different densities, the hydriodic acid is in the upper layer, and the selenous acid solution is in the lower layer. Using a liquid-liquid separation method, the selenous acid solution and hydroiodic acid are subjected to liquid-liquid separation to obtain the selenous acid solution and hydroiodic acid;
[0038] (2) contain following component in the hydroiodic acid that step (1) obtains: 1 2 , HI and H 2 O, the mixed ternary solution is r...
