This paper introduces a method for recovery of potassium iodate from wastewater containing iodine.Potassium iodate is obtained by neutralization with potassium hydroxide,using barium chloride as precipitant and concentrated sulfuric acid as oxidant.The results show that this method is simple and easy for operation with large amount of wastewater treated and quick speed of recovery.The reagents used are inexpensive and non-toxic,and no harmful substances are produced.The recovery rate of iodine from waste water is more than 90% and the purity of potassium iodate is more than 99%.
