Iode : Procédés d'extraction et cas industriels

À partir des caliches, l'iode est lixivié puis récupéré par flottation, extraction dans du kérosène, entraînement par soufflage d'air (« blowing out process »). L'iode …

How to recover iodine more efficiently? Extraction of triiodide

An efficient process was proposed for the recovery of iodine via solvent extraction of triiodide (I3⁻) when 21% of I⁻ was oxidized. I3⁻ and I⁻ rather than I2 were …

A novel and complete process for iodine extraction and …

Using 30% H 2 O 2 as an oxidant, all the iodides ions present in wet phosphoric acid was converted into elemental iodine. The iodine was then extracted and stripped quantitatively using pure kerosene and 0.02 M sodium sulfite at ratios (O:A) of …

How to recover iodine more efficiently? Extraction of triiodide

Although it is simple to operate, the extraction is inefficient to utilize low-grade iodine resource because of the incomplete oxidation or peroxidation of iodide ion. …

Extraction

Assume that the iodine distributes itself between the water and chloroform layer in a ratio of 1:9 respectively. This means that one extraction will remove 90% of …
