中文摘要:

      对国内外提碘技术的主流工艺——空气吹出酸液吸收法的工艺特点及生产现状进行了分析。应用超重力强化提碘技术对I₂-HPO₃-H₂O体系进行游离碘吹脱实验。在实验控制的参数条件下,总碘浓度为35 mg/L和45 mg/L的氧化液单级吹脱率分别为78.24％和91.27％。本研究结果对综合回收磷矿中伴生的超低品位碘资源有较大实用意义。

英文摘要:

      :The process features and the present situation of iodine production using traditional air blow out process were studied in our experiments,supergravity iodine preparation technology applied in the extraction free iodine from I₂-HPO₃-H₂O system. In the control parameters,the iodine extracting rates of liquid ingredients which total iodine concentration of 35 mg/L to 45 mg/L obtained to be 78.24% and 91.27%,respectively. It is practical significance that the results of this study to comprehensive of low grade iodine associated phosphate rock resources recovery.
