Alternative Routes to Chloromethylation for Preparation of Anion Exchangerssins were prepared based on the chemistry of polyamine epoxy, acrylic epoxy and phenolic epoxy with epichlorohydrin. Samples of strong, weak and mixed basicity with varying characteristics were made for water treatment applications. Pilot plant samples show promising results in laboratory operating

Multi-Component Mixed-Bed Ion Exchange Modeling in Aminated Watersase reaction to determine mixed-bed effluent-concentration profiles. The cationic resin is initially in the hydrogen form. As exchange progresses, the hydrogen cycle is replaced by the amine cycle which produces a characteristic of amine form operation, sodium throw. The model predicts the transient

Leachables from Cation Resins in Demineralization and Polishing Plants and their Significance in Watat due to ageing. The former can be largely removed by thoroughly cleaning of new resins before use. This paper focuses on cation resins. Even though the anion resins remove some of the leachables, the remainder enters the water/steam circuit of the boiler, where due to the high pressure and tempera

R. T. Stringfield,P. A. Andreozzi,R. R. Stevensd Brasilien. Ab Ende der 1990er Jahre begann sich in Lateinamerika eine politische Linkswende abzuzeichnen, deren gemeinsamer Nenner in der Abkehr von neoliberaler Politik bestand. Davon abgesehen unterschieden sich die eingeschlagenen Wirtschaftspolitiken jedoch beträchtlich. Während Venezuela eine

Preparation of Chelating Hollow Fibers Based on Chlorosulfonated Polyethylene and its uses for MetalDifferent anion-exchange and chelating fibers were prepared from chlorosulfonated polyethylene, to which amine groups were attached. The chemical reactions of amination, quaternization and carboxylation were carried out under different conditions, and the relationship between the properties of fibers and their structure was established.
