Abstract : this paper describes a new preparation technique of calcium iodate . at the presence of hydrochloric acid , iodine is oxidated by sodium chlorate , and then reacts with calium hydroxide . a series of constrasted experiments are made on the conditions and different techniqures . relatively high productivity and purity at low cost . easy controllability and operation are the main features of this kind of technique 文摘:介紹了以單質碘為原料,在鹽酸存在下,經氯酸鈉氧化,再與氫氧化鈣進行中和反應制備碘酸鈣的方法,并做了最佳工藝條件和不同方法的對比實驗.本法具有收率較高、純度較高、生產成本較低及反應條件易控制、設備簡單、操作方便等特點

By adopting the iodide - iodate reaction system as an index , the distribution of segregation index ( x ) along the radial direction of packing and the effects of different operational conditions ( e . g . rotational speed , flow rates ) on micromixing efficiency of a novel rotating packed bed ( rpb ) have been investigated 通過設計一臺能實現沿程取樣的旋轉填充床,同時通過采用一種平行競爭微觀混合體系碘化物碘酸鹽反應體系,考察了填料的不同徑向位置離集指數的分布及各操作參數對旋轉填充床微觀混合效率的影響。

The proposed method has been applied to the analysis of water samples from several sources , the recoveries of the hexavalent chromium added to the samples are quantitative , and results found are satisfactory . based on oxidation of iodide to iodate and collection of ion - associate produced by tri - iodide with cation surfactant ctmab , and a subsequent spectrophotometric method is described for sensitive and selective determination of the resulting solution owing to dissolving the membrane and analyte in an organic solvent 在ph1 . 5的條件下,溴定量氧化碘離子最終生成的碘三離子,再與ctmab完全反應生成的離子締合物可以被膜富集,膜和富集物溶于小體積的有機溶劑后,加入0 . 1ml3mol l的硫酸抑制滯留在膜上的碘離子在有機溶劑中被空氣中的氧氣氧化而造成吸光度不穩定。

In addition to iodide and iodate , another iodine compound could be separated and detected in certain samples with high total iodine concentrations and was identified as elemental iodine , probably in form of triiodide , by peak matching 在碘化合物總濃度很高的特定樣品中,除了碘化物和碘酸鹽,其他的碘化合物也可以被分離和檢測,其通過峰匹配以三碘化物形式被做為元素碘檢出。
