Полученный раствор бисульфита магни анализируют.The resulting solution of magnesium bisulfite is analyzed.
В этих же услови х дл сравнени раствор бисульфита магни готов т без предварительного насыщени углеродноХарактеристика раствора бисульфита магни Under the same conditions for comparison, a magnesium bisulfite solution is prepared without pre-saturation of carbon. Characteristics of a magnesium bisulfite solution
го материала двуокисью серы согласно известному способу.sulfur dioxide according to a known method.
В табл. 1 приведены данные, характеризующие описанный процесс.In tab. 1 shows the data characterizing the described process.
ТаблицаTable
Степень извлечени МдО рассчитыва лось по максимально возможному количеству МдО в растворе в этих услови ( при двухчасовой экстракции). Концентраци св занной 50 определ лась по условному со- держанию в растворе моносульфита MoSO .The degree of extraction of MDO was calculated by the maximum possible amount of MDO in solution under these conditions (with a two-hour extraction). The concentration of the bound 50 was determined by the conditional content in the MoSO monosulfite solution.
Характеристика раствора бисульфита магни Characteristics of magnesium bisulfite solution
Как видно из приведенных выше таблиц , предварительное насыщение углеродного материала, содержащего окись МсЦнн , двуокисью серы, значительно гс сокращает врем экстракции окиси магни при получении раствора бисульфита маСни . Сокращение времени экстракции дает возможность либо повысить производительность адсорбционного оборудовани , или же использовать обору- 60 дование меньших габаритов при заданной производительнЪсти.As can be seen from the above tables, the pre-saturation of carbon material containing MgSnn oxide with sulfur dioxide significantly reduces the time of extraction of magnesium oxide when preparing a Masn solution of bisulfite. The reduction in the extraction time makes it possible either to increase the productivity of the adsorption equipment, or to use equipment of smaller dimensions at a given productivity.

Таблица 2table 2
ного материала (пример 2), предварительно насыщенного двуокисью серы, врем экстракции МдО сокращаетс в 1,5-2 раза по сравнению с процессом, в котором насыщение углеродного материала двуокисью серы не, проводилось.Example 2, pre-saturated with sulfur dioxide, the extraction time of MDO is reduced by 1.5–2 times compared with the process in which the carbon material was not saturated with sulfur dioxide.
