“…Based on the previous reports and recent researches the following advantageous of solvent sublation can be outlined: 1) high separation efficiency; 2) high concentration coefficient; 3) low dosage of organic solvent; 4) soft separation process; 5) simple operation and equipment [5]. Moreover, this technique provides the possibility of the further dye recovery after its elimination [6][7][8][9][10][11][12][13]. The removal of IC, an anionic dye from aqueous solution by solvent sublation was studied.…”

In this research, which includes the previously published works of this team on dyes removal, solvent sublation was applied in order to remove such dyestuff as Indigo carmine from model solutions. The aim of the work was to study the main principles of Indigo carmine removal from water by solvent sublation. Indigo carmine (IC, C 16 H 8 N 2 Na 2 O 8 S 2 ), an anionic dye, was removed from aqueous solutions by solvent sublation of an IC-hexadecylpyridinium bromide (HPB) complex (sublate) into octanol. The effects of the following parameters on solvent sublation were experimentally studied: the molar ratio of HPB:IC, pH of aqueous phase, duration of the removal process, type and volume of organic solvent. The initial dye concentration was 10 mg/dm 3 .It was found that the process should be conducted under such conditions: pH 5, solventoctanol, Schott filter nominal pore size -16 µm, molar ratio of HPB:IC = 1:1, process duration -20 min. According to obtained results the highest level of IC elimination that was reached within the experiment equals 95,5 %.
