Separation of Tellurium from Iodine with Anion Exchange Resin

An anion exchange resin from soybean hulls

Agricultural by-products are generally poor adsorbents of anions in solution. Therefore, modification of the by-product could enhance its anion exchange capabilities. The objective of this study was to increase the anion exchange properties of the agricultural by-product, soybean hulls, by chemical modification. Soybean hulls were quaternized with the quaternizing agent, N-(3-chloro-2hydroxypro...

Separation of Hafnium From Zirconium by Anion Exchange

G . H evesy has written that [6] 1 " In view of the I.great similarity b etween hafnium and zirconium, i t ris hardly possible to separate these two elements in a lsingle operation ." A simple one-step separation c adequ a te for analytical work has still to be developed for hafnium-ziTconium mixtures, although recent work employing ion exchange has developed suitable methods for the separation...

Procedure to Reduce Sulphite in Wine with Anion-exchange Resin

HORÁK, M., HÍC, P., TOMÁNKOVÁ, E., BALÍK, J.: Procedure to reduce sulphite in wine with anion-exchange resin. Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 8, pp. 79–86 The aim of this experiment was to eliminate SO2 ions present in wine using the anion-exchanger resins. To compare the eff ectiveness, 2 following strongly basic anion-exchange resin were used. When activated, the sod...

Extraction of Carbon Dioxide from Sea water by Ion Exchange Resin Part II: Using Strong Base Anion Exchange Resin

Kinetics study on separation of cadmium from tellurium in acidic solution media using ion-exchange resins.

The feasibility of using ion-exchange resins to separate cadmium from tellurium in acidic solutions of the two metals was investigated. We studied the competitive adsorption of cadmium and tellurium in such resins under varying acid strengths and contact time. We found that low sulfuric acid strength (i.e., 0.5 M) was most effective in removing cadmium from solutions. Different ion-exchange res...
