Simultaneous determination of titanium and molybdenum in alloy steels using derivative spectrophotometry in neutral micellar medium
A simple, selective and sensitive spectrophotometric method has been developed for the individual and simultaneous determination of Ti(IV) and Mo(VI) using salicylaldehyde p-hydroxybenzoylhydrazone (SAPHBH) in presence of Triton X100, without any prior separation. Beer’s law is obeyed between 0.15-2.0 and 0.20-2.51 μgmL concentration of Ti(IV) and Mo(VI) at 470 and 410 nm, respectively. The mol...

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Micellar medium for the analysis of complex mixtures of molybdenum and tungsten by derivative synchronous spectrofluorimetry in steels.
The cationic surfactant hexadecyltrimethylammonium bromide enhances the fluorescence intensity of both molybdenum and tungsten complexes obtained with Alizarin Red S. This characteristic has been used for a sensitive simultaneous spectrofluorimetric determination of both ions over the range 32-4000 ng/ml and 49-2500 ng/ml for Mo and W, respectively. Good selectivity is achieved applying the wel...
متن کاملInvestigation and Determination of Osvix by Gold Nanorods by Spectrophotometry
Background and Aims: Osvix drug is an internal brand of Plavix, which is used to prevent blood coagulation in many heart diseases. The aim of the present study was to measure this drug by gold nanorods in optimum conditions and in real samples. Material and Methods: Gold nanorods were synthesized by the seeded-mediated method. Measurement of Osvix drug by gold nanorods was performed by optimizi...
متن کاملDetermination of traces of phosphorus in steels by laser ablation/ low-pressure helium-ICP-MS.
coupled plasma–mass spectrometry (ICP-MS) offers a powerful and rapid analytical method for different solid samples (e.g., rocks,1–3 metals,2,3 and ceramics3), the mass spectral interference often becomes a serious problem.4 For example, the determination of phosphorus (31P, monoisotopic element) is disturbed by 14N16OH+ and an adjacent large background peak of O2, which mainly originates from ...
