卤水中碘离子的氧化行为研究

Abstract

Abstract: The oxidation behavior of iodide ions contained in nature brine to iodine was studied by spectrophotometric method with two different oxidants（0.5% NaClO and 1.0% H₂O₂， mass fraction）.The optimal dosage of NaClO and H₂O₂ were deter- mined to be 0.6 mL and 1.7 mL every 200 mL brine，corresponding to the optimal pH of 4.8 and 3.0，and the optimal reaction time of 30 min and 70 min，respectively.The excessive oxidation problems of iodine by these two oxidants were also investigated and the relationship between absorbance and excessive oxidation degree of iodine was given in this paper.

Key words: nature brine, oxidation behavior of iodine ions, spectrophotometry
