Abstract:
In a cartridge for removal of impurities from water, an elongated tube is charged, between water-permeable barriers, with ion exchange resin of a type capable of removal of bacteria from water. Outside one such barrier, an inlet cap is charged with water-soluble bactericide in a shelf-stable, water-activatable form. Preferably, the bactericide is sodium salt of dichloroisocyanuric acid, in granular form.
Abstract:
The disclosure is of the extraction by ion exchange and use, especially in edible materials, of functional protein material having one or more useful surface-active properties such as foaming, foam stabilization, gelation, or water-or fat-binding characteristics.
Abstract:
An absorption process of using polydivinylbenzene to remove nerve agents h as GD from a conventional solvent such as chlorofluorocarbon which itself is used to decontaminate a surface such as armament.
Abstract:
A composite containing DEAE-cellulose agglomerated with a hydrophobic polymer is treated with tap water, deionized water or a dilute salt solution at a temperature of at least 60.degree. C. for a time sufficient to increase adsorption capacity for charged macromolecules by at least about 30%. Treatment is preferably at a temperature of about 80.degree. to about 100.degree. C. for a time period of about one-half hour to about 5 hours. The macromolecule is preferably a protein such as the enzyme, glucose isomerase.
Abstract:
A process for separating basic amino acids from a liquid containing the same using cation exchange resin towers in series, which comprises effecting repetitive adsorption and elution steps in sequence, wherein the washing water employed in said adsorption and elution steps is obtained by recycling the latter portion of a liquid discharged from a first tower of the adsorption step into an adsorption step in a subsequent cycle, or by recycling a liquid discharged from a first tower at the elution step into an elution step in a subsequent cycle.
Abstract:
A method is disclosed for removing certain contaminant phospholene and phospholane oxides or sulfides from organic fluid or fluid mixtures wherein the fluid or fluid mixture is contacted with a cation exchange resin insoluble in the mixture at a temperature of from about 20.degree. C. to about 100.degree. C.

Abstract:
Waste waters, particularly waste waters with radioactive contamination, are cleaned by a sorption-precipitating process, where the sorbent retaining cations are regenerated that is, activated, by a solution, the cationic component of which forms with anionic contaminations a precipitate, taking along cationic contaminations, and simultaneously sticking on the surface and within pores of the sorbent.
Abstract:
A method of separating proteins by ion exchange comprising putting a solution of proteins into contact with an ion exchange resin consisting of a porous inorganic carrier coated with a cross-linked polymer containing or carrying anion exchanging groups -- tertiary amines or salts of quaternary ammonium -- or cation exchanging groups and application of the process to the food, pharmaceutical and veterinary field.
Abstract:
An endotoxin adsorption system of the present invention comprises a combination of a cation exchange resin having sodium as a counter ion and a cation exchange resin having sodium and one or more metal ions other than sodium as a counter ion, and adsorbs an endotoxin without decreasing of the concentration of cations.
