Abstract The study of the separation of metallic chlorides on Amberlite CG-120 (200–400 mesh) cation exchange resin was continvied. Na, K, Mo, Al, Ca, and Fe have been separated by hydrochloric acid solutions and determined by polarography or flame photometry. Semimicro quantities of these metals can be separated from each other with a minimum of eluting agent, small resin beds, and simple equipment. Mechanical grading of the air-dried resin was used to obtain more uniform particles. The ion exchange separation scheme offers advantages over present official procedures, and it should provide a unified method for the analysis of metals in mixtures. Further study is recommended.

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.

It was found that the ion exchange resins Purolite C100 H and Purolite S-957 can be used to extract lanthanum (III) ions from solutions. The values of the resin capacities for lan-thanum (III), iron (III) and aluminum and the ion distribution coefficients for both resins were determined. It is shown that according to the values of the separation coefficients, Purolite C100 H resin can be used for ion exchange separation of lanthanum ions from complex solutions

Ion Exchange Process

Abstract Industrial waste solutions may contain toxic Pb, Cu, Cd and other metal ions. These ions may also be components of leachates in landfills of ores. The toxicity of the ionic forms of these metals is high. For this reason the paper presents the results of studies on one of the methods to reduce their concentration in aqueous solutions. The article presents the results of studies on the removal of Pb2+, Cd2+ and Cu2+ ions from model aqueous solutions with synthetic ion exchange resin C 160 produced by Purolite. The investigated ion exchanger contains sulfonic acid groups (-SO3H) in its structure and is a strongly acidic cation-exchange resin. The range of the studied initial concentrations of the Pb2+, Cd2+ and Cu2+ ions in the solutions was from 6.25 mg/L to 109.39 mg/L. The results confirmed that the used ion exchange resin C160 efficiently removes the above-mentioned ions from the studied solutions. The highest degree of purification was achieved in lead solutions for the assumed range of concentrations and conditions of the ion exchange process. It reached 99.9%. In the case of other solutions, the ion exchange process occurs with lower efficiency, however it remains high and amounts to over 90% for all the ions. The results of research were interpreted on the basis of the Langmuir adsorption model. For each studied ion, sorption capacity of the ion exchange resin increases until the saturation and equilibrium state is reached. Based on the interpretation of the Langmuir equation coefficients, an indication can be made that the studied ion exchange resin has a major sorption capacity towards the copper ions. In their case, the highest value of constant qmax was obtained in the Langmuir isotherm. For Cu2+ ions it was 468.42 mg/g. For Pb2+ and Cd2+ ions, this parameter reached the values of 112.17 mg/g and 31.76 mg/g, respectively. Ion exchange resin C 160 shows the highest affinity for the Pb2+ ions. In this case, the achieved value of coefficient b is highest and equals 1.437 L/mg.
