This paper used the ion exchange resin method to treat the heavy metal ion Cu2+ of a chemical wastewater and studied the flow velocity, pH and the temperature’s effect on Cu2+ removal effect by macroporous strongly acidic styrene type cation exchange resin D001. The results shown that: when the flow velocity was 1.5 mL/min, pH was 6.0 and the temperature was 30°C, the removal rate of Cu2+ by D001 reached 99.8%. The chemical wastewater could achieve the wastewater’s discharge standard.

Actual Performance

Electrodialysis and electrodeionization are separation processes whose performance depends on the quality and properties of ion-exchange membranes. One of the features that largely affects these properties is heterogeneity of the membranes both on the macroscopic and microscopic level. Macroscopic heterogeneity is an intrinsic property of heterogeneous ion-exchange membranes. In these membranes, the functional ion-exchange component is dispersed in a non-conductive binder. The functional component is finely ground ion-exchange resin particles. The understanding of the effect of structure on the heterogeneous membrane properties and behavior is thus of utmost importance since it does not only affect the actual performance but also the cost and therefore competitiveness of the aforementioned separation processes. Here we study the electrokinetic behavior of cation-exchange resin particle systems with well-defined geometrical structure. This approach can be understood as a bottom up approach regarding the membrane preparation. We prepare a structured cation-exchange membrane by using its fundamental component, which is the ion exchange resin. We then perform an experimental study with four different experimental systems in which the number of used cation-exchange particles changes from 1 to 4. These systems are studied by means of basic electrochemical characterization measurements, such as measurement of current–voltage curves and direct optical observation of phenomena that occur at the interface between the ion-exchange system and the adjacent electrolyte. Our work aims at better understanding of the relation between the structure and the membrane properties and of how structure affects electrokinetic behavior of these systems.

The aim of this study is to examine the possible use of ion-exchange resin on Dowex AG 50x8 in separating Y-90 from Sr-90 which then could be applied in the basic of manufacture of producing Sr-90/Y-90 generator for the production of radiopharmaceutical cancer therapy. The findings showed that a distributive coefficient of Sr-90 and Y-90 with HCl 6 N solvent showed that distributive coefficient of Sr-90 in cation-exchange resin on Dowex 50x8 was greater than Y-90. Y-90 in HCl 6 N solvent was more easily eluted, while Sr-90 was bound to resin.. In conclusion, resin on Dowex AG 50x8 with HCl 6 N elution solvent might be able to separate Y-90 from Sr-90 as the basis for Sr-90/Y-90 generator.

Abstract A convenient screening procedure for presence of drugs of abuse in urine consists of two steps: adsorption of the drugs from urine onto a paper loaded with cation-exchange resin and detection of the adsorbed drugs by direct radioimmunoassay. The first step can be performed in the field, the second in a central laboratory. Storage and transport to the laboratory are simplified because specimens adsorbed on dried paper are stable and can be sent in letter-mail. In the laboratory, a small disc of the ion-exchange paper is exposed to antigen and antibody, rinsed, and tested for radioactivity. Discs treated with positive urines are more radioactive than discs from negative urines.

Ion Exchange Method

Abstract An ion exchange method to determine the alkalinity of water-soluble tea ash containing high levels of manganese is described. A chromatographic column containing a strong cation exchange resin (20–50 mesh) in Na+ form, with a bed volume of 5 mL is used. The present ion exchange method is compared to pH titrations and also to the official AOAC methods (31.012, 31.015, 31.016). Results with the new method are accurate and precise.
