A new kinetic spectrophotometric method for the determination of micro amounts of iodine was developed based on the principle that I - inhibits the discoloration of metanil yellow oxidized by potassium bromate in sulfuric acid medium in the presence of sodium thiosulfate.
在硫代硫酸钠存在下的硫酸介质中，碘对溴酸钾氧化间胺黄褪色具有抑制作用，建立了测定微量碘的新方法。
Among them, 867 were given endoscopy examination during which mucosal stain with 1.2% iodine solution was used. The stain images were graded as four categories: Grade 1, dark yellow, protruding inlay like with clear borders and showing pink after discoloration;
内镜检查时采用1.2%碘液黏膜染色，染色图像分为4类：第Ⅰ类：深黄色，隆起感，边缘清楚嵌入状，退色后呈粉白色；

溴酸钾氧化酸性间胺黄动力学光度法测定食品中微量碘
Comprehensive treatment of yellow phosphorus wastewater and iodine recovery from the wastewater;
最后，指出今后黄药废水处理的发展方向。
Iodine shows the different colours, such as purple、red、brown、and yellow ect, in different organic solvent.
碘在不同的有机溶剂中能够形成紫、红、棕、黄等颜色的溶液。
