Extraction of Uranium(VI) from Bicarbonate-Oxalate Leach Solution 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...

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

Extraction of [18F]fluoride from [18O]water by a fast fibrous anion exchange resin.

[18F]Fluoride for nucleophilic radiofluorination was recovered from target water by trapping on a fibrous anion exchange resin in the hydroxide form and subsequent displacement into wet methanolic K2CO3. Extraction into methanol facilitated rapid evaporation and resolubilization of the [18F]fluoride as an ion pair. The resin was first dried in situ and rehydrated with [18O]H2O to avoid isotopic...

Cholangiocyte anion exchange and biliary bicarbonate excretion.

Primary canalicular bile undergoes a process of fluidization and alkalinization along the biliary tract that is influenced by several factors including hormones, innervation/neuropeptides, and biliary constituents. The excretion of bicarbonate at both the canaliculi and the bile ducts is an important contributor to the generation of the so-called bile-salt independent flow. Bicarbonate is secre...

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...
