Complexometric Analysis of Multicomponent Systems
Methods of complexometric analysis are reviewed with particular reference to their improved potential due to recent developments in theory and instrumentation. It is shown how accuracy has been improved and how reactions leading to the formation of compounds with rather low stability constants can be utilized successfully. For the analysis of multicomponent systems there are essentially two pos...

15 صفحه اولQuantitative Determination of Carboxyl Groups in Cellulose by Complexometric Titration
Complexometric titration was used to determine the carboxyl group content of a series of oxidatively treated (selective and non-selective oxidation) nature cellulose fibers (cotton). The results were correlated with those obtained from the conventional methylene blue method; both methods show an excellent correlation. The progress of the cellulose fibers oxidation was monitored using viscosimet...
