It is interesting that DOM-WS can obviously enhance the fluorescence intensity of Eu(III)–thenoyltrifluoroacetone–cetyltrimethyl ammonium bromide system. On the basis of this study, a new fluorescence method for the determination of trace amounts of Eu(III) was developed. Under the optimal ...
Cetyltrimethylammonium bromide(CTAB; 2.5g, 6.87mmol) was dissolved in water (85g), and to this solution Zr(SO4)24H2O (4.55g, 0.0128mol) dissolved in water (25g) was added[9]. This led to a colorless precipitate. The mixture was stirred at room temperature for 2h and then placed in ...
It decomposes on heating at 60°C, releasing carbon dioxide, ammonia and water vapour in a temperature-driven reaction. All three products act as bulking agents. As ammonia is dissolved in water, it can be retained in moist products, giving them a sharp, pungent odour that renders them ...
