The Use of Tetramethylbenzidine as an Indicator in the Enzymatic Quantitative Determination of Ethonium

Журнал органічної та фармацевтичної хімії
The study considers the possibility of using 3,3',5,5'-tetramethylbenzidine (TMB) as an indicator in the enzymatic analysis for the quantitative determination of quaternary ammonium compounds on the example of ethonium. The feasibility of using TMB as an

Composition and structure of ammonium uranates

, 1968
The ammonium uranate system was studied by thermal analysis, ion-exchange measurements and infra-red spectroscopy. The results show that in all ammonium uranates, ammonia is combined as NH4+. Infra-red results indicate that the ammonium uranate system is
