Resin-supported [18F]fluoride ion has been prepared and applied to a rapid, convenient synthesis of [18F]FDG. "No-carrier-added" [18F]fluoride ion is collected on a quaternary 4-(N,N-dialkylamino)-pyridinium functionalized polystyrene anion exchange resin directly from a [18O]water target, dried by rinsing with acetonitrile, and then reacted with 1,3,4,6-tetra-O-acetyl-2-O-trifluoromethanesulfo...

Experiments are described showing that an anion exchange resin may be used as a simple means of determining the amount of free radio-activity in emulsions of triolein and oleic acid labelled with (131)I in the form of (131)ICl. In the case of radio-iodinated triolein no special modifications are necessary. With radio-iodinated oleic acid, the working solution is made up with an excess of unlabe...

Serum labelled with (59)Fe for ferrokinetic studies should contain only [(59)Fe] transferrin. [(59)Fe] ferric citrate was incubated at 37 degrees C for up to 24 hours with sera having an excess latent iron-binding capacity. The results showed that unbound [(59)Fe] ferric citrate may be present for several hours. An anion exchange resin (IRA 400 Cl(-)) column removed all the [(59)Fe] ferric citr...

The use of cellulose-containing agricultural by-products modified with the cross-linking reagent dimethyloldihydroxyethylene urea (DMDHEU) and the quaternary amine, choline chloride, as anion exchange resins, has not been reported. The objective of the present study was to convert the readily available by-products, soybean hulls, sugarcane bagasse and corn stover to functional anion exchange re...

Cancer therapy with oncolytic measles virus (MV) requires high titers of pure, infectious particles (~108 times more per dose than the vaccine). A gentle but efficient downstream purification process is therefore essential. Here we investigated suitability ion-exchange chromatography for MV using resin-based stationary phases. The success was evaluated based on yield, ratio to total particles, ...

The objective is to concentrate organic acid traces in water samples. The influence of several parameters and their interactions on the adsorption of organic acids on anion exchange resins was studied. A complete factorial design 24 was hence performed. The measured response corresponds to the maximal percolation volume and the studied parameters were the nature and the mass of the resin, the p...

Take the ethylene-vinyl alcohol (EVAL) copolymer as the infrastructural material, the anion exchange resin D301R as the functional grains, adopt dry-wet method to make resin-filled EVAL hollow fiber membrane, test the pure water flux of the membrane, the rejection rate of the bovine serum albumin (BSA) and the static absorption performance of BSA. Check the influences of coagulation bath temper...

This work describes a methodology for the valorization of non-food biomass production biosourced molecules via biohydrogen and metabolites fermentations such as volatile fatty acids. The commercial anion exchange resin Amberlite IRA-400(Cl) was chosen extraction carboxylic Different operating conditions were set up namely amount to be used, activation methods, pH their effects on capacity solve...
