Summary. A new selective , sensitive, and simple kinetic method is developed for the determination of trace amounts of iodide. The method is based on the catalytic effect of iodide on the reaction ...
kinetic methods have been reported for the oxidation of Naphthol Blue Black, with potassium determination of manganese(II) based on its catalytic periodate in the presence of 1,10-phenanthroline effect ...
(pheomelanin‐ based ) coloration may act as an honest signal of individual quality. To test this prediction, we spectrophotometrically measured brightness (an indicator of total melanin content) and red chroma ...
ABSTRACT A new sensitive and selective disposable potentiometric sensor based on polypyrrole (PPy) films for determination of sildenafil citrate (SC) was proposed. The pyrrole polymerization ...
). All extracts were evaluated both spectrophotometrically ( determination of total phenolic content (TPC) and antioxidant activity by ABTS and FRAP assay) and chromatographically (HPLC-UV). NADES based ...
in aqueous medium at pH 3.00–10.73 at I = 0.5 mol dm−3 (LiClO4) spectrophotometrically and through 1H NMR spectral analysis. The selectivity of platinum(II) toward the amino acids with regard to chelation ...
of its 3D distance from the cluster centre. The number of stars in the cluster, right after the kick, was determined so that the bound stellar mass would amount to: $$\begin{eqnarray*} M_{b} = 11.6\gamma ...
spectrophotometric procedure for the quantification of commercial sunscreens in seawater. The method is based on the properties of these cosmetics to absorb UV radiation; it requires no sample pretreatments ...
between HDL protein concentration and PON1 activity as determined by the established spectrophotometric method (○) and the new microtiter plate method (•; A), and serum PON1 activities as determined ...
that DBS SS cards could be used to determine vibriocidal titers from DBS samples using both spectrophotometric and chromogenic dye- based methods, and that they are stable across a range of storage ...
