Resin Separation

Abstract The metals Mn, Mg, Co, Cu, and Zn were separated by using an anion exchange resin column and progressively less concentrated IIC1 solution as eluting agent. The position of Mg on an anion exchange resin, not previously reported in the literature, was determined. It has been shown that by using two different ion exchange resin columns, simple hydrochloric acid solutions as eluants, and polarographic or flame photometric determinations, 12 metals can be separately estimated in an aqueous solution containing about 100 /μg of each. It is recommended that the study of ion exchange resin separation of metals found in plants be continued.

SummaryA flow method during reactor irradiation to separate the recoiling species from the parent complex ion adsorbed on an ion-exchange resin was applied to the trioxalatochromium ion. The separable yield increased as expected: 80% for the dynamic method compared with 66% for the static method, at

Aqueous Hydrogen Peroxide

The technologies of ion exchange resin for ultra pure hydrogen peroxide production are more and more focused.The aim of this research was to select suitable parmeters for effective removal of P ion impurities from the experimetal aqueous hydrogen peroxide solution to produce ultra-pure hydrogen peroxide. Dynamic experiments for the different operation conditions, i.e., initial concentrations, flow rates, ratios of height to diameter were carried out. The concentrations of P anion of the effluent samples from the anion exchange resin column were determined by ICPS-7510.The breakthrough curves of P ion were measured and analyzed. The results showed that P ion could be reduced effectively from the experimetal aqueous hydrogen peroxide solution with the fitting conditions of ion exchange resin column, It provided the basis for determining of the suitable operating conditions of ion exchange column of commercial plant.

Borate ion exchange capacity of Purolite NRW600 strong base anion resin in hydroxide form and mixed bed NRW600+NRW100 ion exchange was investigated with static experiments. Anion exchange resin was saturated with 0.1–45 g/dm3 concentration boric acid solution in a static mixer at 20, 30, 40 and 50 °C at 150 rpm for 24 hours. Remaining borate content of saturation solutions was deter-mined with ion chromatography and ICP-OES. The amount of fixed borate as borate anions increased with the saturation borate concentration as well as in case of simple anion exchange as in case of mixed bed.Column sorption-elution study was carried out by using strong base anion exchange resins (Purolite NRW600 and Amberlite IRN78). Resins in hydroxide and in chloride forms were saturated in column with 5–40 g/dm3 boric acid solution in excess. The resin was then eluted with 200 cm3 salt free water with 5 cm3/min at 25 °C and then eluted by 1 mol/dm3 sodium-sulfate solution with 5 cm3/min. The effluent was collected and analyzed for borate content by titrimetric method. In chloride form the resin adsorbed and released much less borate. Effective borate and polyborate sorption needs hydroxide ions in resin phase.
