黄磷生产废水中碘的提取实验研究与机理探讨

On Extracting Iodine From Wastewater Of Yellow Phosphorus of the Mechanism of Research and Experimental study

针对含碘60-140 mg/l的循环水进行提碘回收实验,得到含95%-98%粗碘。通过设计正交实验测出不同条件下吹出液中的碘含量,进而求出其对应的吹出率,采用极差分析得出回收黄磷废水中碘的最佳工艺条件。

For the circulating water with the iodine density is about 60 - 140mg/l in circulating water, an experiment on extracting iodine has been performed, and crude iodine with 95 % - 98 % iodine content has been obtained. Iodine density under different conditions can be tested through orthogonal experiments, further their rate of blowing out and rate of recovery can be calculated, thencalculated, then through range analysis to master the optimum technology conditions of reclaiming iodine from waste water of yellow phosphorus.
