Description

-СЦ2-С11 +OS05 lHi -S-UH.-SC2-C11 + OS05 lHi -S-UH.

обладающий флокулирующим свойством.having a flocculating property.

К 1000 мл исходного раствора добавл ют 100 мл 0,5%-ного раствора крахмала и различное количество 0,1%-ного раствора вышеприведенного флокул нта. Суспензию отстаивают в течение 20 и 240 мин, содержание иода в продуктах сгущени  определ ют по стандартной методике.100 ml of a 0.5% starch solution and a different amount of a 0.1% solution of the above flocculant are added to 1000 ml of the initial solution. The suspension is settled for 20 and 240 minutes, the iodine content in the thickening products is determined by the standard method.

Дл  сравнени  проведены опыты с применением только крахмала. Результаты этих опытов, приведенные в таблице, показывают , что совместна  обработка раствора иода крахмалом и ППС существенно увеличивает извлечение иода и скорость выделени  иодо-крахмальной взвеси из жидкой фазы по сравнению с обработкой раствора иода только крахмалом.For comparison, experiments were performed using starch only. The results of these experiments, shown in the table, show that the combined treatment of the iodine solution with starch and PPS significantly increases the recovery of iodine and the rate of release of iodine-starch suspension from the liquid phase compared with the treatment of iodine solution only with starch.

Claims (2)

Формула изобретенияClaim 1. Способ извлечения иода из водных растворов путем обработки их крахмалом с последующим отстаиванием иодо-крахмальной взвеси и выделением продукта, отличающийся тем, что, с целью повышения извлечения и снижения времени отстаивания, после обработки крахмалом вводят полимер соли 2-метил-5-винилпиридина и диметилсульфата.1. The method of extracting iodine from aqueous solutions by treating them with starch, followed by settling iodine-starch suspension and isolation of the product, characterized in that, in order to increase the extraction and reduce the time of settling, after treatment with starch, the polymer is introduced 2-methyl-5-vinylpyridine and dimethyl sulfate. 2. Способ по π. 1, отличающийся тем, что крахмал и полимер соли 2-метил5-винилпиридина и диметилсульфата берут в соотношении 100 : (1—7).2. The method according to π. 1, characterized in that the starch and polymer salts of 2-methyl 5-vinylpyridine and dimethyl sulfate are taken in a ratio of 100: (1-7).
