Determination of thallium(I) by flotation-spectrophotometric method using iodide and rhodamine B.
A method for the trace amount determination of Tl(I), via its preconcentration, is proposed. The method is based on the reaction of iodide, Tl(I) and Rhodamine B in a weakly acidic medium. In this process an ion-associated complex is formed, which is floated at the interface of aqueous-cyclohexane layers. Various amounts of Tl(I) by a subsequent separation and dissolution of the floated complex...
متن کاملPhotometric Determination of Estrogens
The Kober color test for the identification of natural estrogens (1) is a 2-phase reaction. The first effect of heating estrogens with the phenolsulfonic acid reagent is the production of a yellowish brown-colored solution; when this solution is chilled, carefully diluted with water, and then reheated, its color gives way to a characteristic pink. The Z-phase nature of the reaction renders its ...
متن کاملPhotometric Determination of Quasar Candidates
We describe an efficient and fast method for the detection and classification of quasars using a machine learning tool, making use of photometric information from SDSS DR7 data release. The photometric information used are the ten independent colours that can be derived from the 5 filters available with SDSS and the machine learning algorithm used is a difference boosting neural network (DBNN) ...
متن کاملPhotometric determination of catalase activity.
Catalase activity may be measured quantitatively by the method of von Euler and Josephson (1) by allowing the enzyme solution to react with hydrogen peroxide for varying periods of time and measuring the excess peroxide remaining by titration with potassium permanganate. The similarity of this titration procedure to the assay of ascorbic acid by titration with 2:6-dichlorophenolindophenol sugge...
متن کاملA Facile Spectrophotometric Method for the Determination of Hypochlorite using Rhodamine B
Um método espectrofotométrico simples, rápido e sensível foi desenvolvido para a determinação de hipoclorito usando Rodamina B. O método proposto considera a reação de hipoclorito com iodeto de potássio em meio ácido, com liberação de iodo. O iodo liberado descora a solução vermelho-rosada de Rodamina B que pode ser medida em 553 nm. Este decréscimo na absorbância é diretamente proporcional à c...
