Description

In the previous report [T. Yamada, J. Chem. Sac. Japan, Ind. Chem. Sect. 57, 421 (1954)], HCO₃form Amberlite IRA-400, a strongly basic anion exchange resin, had been employed, The resin had been able to remove completely the noncarbonate hardness of artificial sea water in composition similar to sea water previously removing magnesium with lime. In this work, another strongly basic anion exchange resin, Amberlite IRA-410, was selected.<BR>I. Equilibrium Study<BR>It was performed to study on the equilibrium between HCO₃, and Cl. Both the selectivity coefficient and the specific exchange capacity of the resin were larger than those of I RA-400 ; hence the resin was expected to be suitable for purification.<BR>II. Purification Study<BR>The resin, which had been previously converted, to HCO₃, form, was agitated with a known volume of artificial sea water (for example, NaCl 27.07g/l, CaCl₂ 6.77g/l) for 2 hours, and the filtrate was analyzed. The Cl-form resin, wet valume 100cc, was able to be regenerated with 500-700cc of 1-1.8 N·NH₄HCO₃,(the same efficiency as IRA-400), and to purify approximately 1.41 of artificial sea water (about 1.7fold amount compared with IRA-400)
