EXTRACTION OF IRON (III) IONS FROM AQUEOUS SOLUTIONS USING TRIBUTYL PHOSPHATE |
摘要 |
FIELD: chemistry.SUBSTANCE: extraction of iron (iii) from an aqueous solution using tributyl phosphate (TBP) is carried out from the aqueous solution with a concentration of 3 n. HCl, 240 g/dmNaCl and a temperature of 60°C by adding TBP in portions with the minimal contact time of the solution and the extractant. Adding the extractant in portions significantly reduces the consumption of the extractant for the virtually complete extraction of iron.EFFECT: cheap and efficient extraction of iron from aqueous solutions.3 dwg, 8 tbl, 3 ex |
