At present, iodine production mainly uses natural gas field water, natural saltpeter ore, oil drilling water and algae plants as raw materials to obtain iodine [3], [4]. Among them, obtaining iodine from seaweed is a good choice, but seaweed is an edible plant, and direct incineration to extract iodine is not only a waste of resources, but also ...Web

The effect of enzymes and other substances on gold bioleaching was investigated. Acinetobacter sp. had a higher gold leaching performance than two strains of Vibrio sp. because it grew well in nutrient broth (NB) medium containing potassium iodide (KI) and produced high levels of both laccase and triiodide (I 3-).Under two-step …Web

Using an oxidative precipitation-SX technique, the quantitative recovery of iodine could be achieved. In the initial step, iodine was precipitated from wastewater using H 2 O 2 as an oxidant. Higher acidity (lower pH) favored iodine precipitation. The optimum iodine precipitation pH was directly related to the iodine concentration in the feed ...Web

The main factor is the reaction progress. A too large amount of lead iodide in the material (due to incomplete reaction) leads to the preferential alteration of this phase with respect to iodoapatite, which will result in a larger amount of leached iodine compared with a ceramic consisting exclusively of iodoapatite.Web

Abstract. Iodine (atomic weight 126.9 g/mol) is an important micronutrient that is required for the synthesis of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). The diet is the primary method of achieving adequate iodine nutrition, with dairy products, some breads, seaweed and other seafood, and iodized salt as the most common ...Web

Turning Iodate Solution Into Iodine. Once the iodate solution is retrieved from the caliche ore, it must be treated to make it suitable for obtaining iodine. To do this, the iodate solution extracted from the ore is divided into two parts. Each part is turned into a "stream" of iodate. Most extraction plants use an SO2 absorption tower ...Web

Iodine. Although seawater is the world's largest iodine reserve, with around 34.5 million tons, no economical direct extraction is feasible because of the extremely low concentrations of this element (less than 0.05 ppm). The main reserves of iodine in brines or caliche ore are in Japan, Chile, USA, Turkmenistan, Azerbaijan and Indonesia.Web
