Determination of Potassium Sorbate and Sodium Benzoate in "Doogh" by HPLC and Comparison with Spectrophotometry
There are various methods for the analysis of Potassium Sorbate and Sodium Benzoate in food products, but a rapid and reliable method for identification of these preservatives in Doogh (an Iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (HPLC) utilized and followed by UV diode array detection of the two preservatives. The aim of this case study w...

concentrations of 42 trace elements, including rare earths, in croatian thermal waters wereinvestigated. originating from different parts of croatia, i.e. different types of aquifers, studied thermal watersprovide insight into the range of concentrations of broad spectrum of elements in croatian thermal waters.covering a wide range of temperature (30 - 92 °c), studied thermal waters are general...
متن کاملRare Gas Mobility in Pure and Doped Potassium Bromide
The mobility of the inert gases argon and xenon in pure and doped single crystals of KBr was studied. The gases were introduced by ion bombardment. The recently established system of stages was used to interpret the results. Normal volume diffusion was found for xenon at low gas concentration, the activation enthalpy being 1.4 + 0.2 eV. This release was independent of doping, thus favoring a tr...
متن کاملCoordination of rare earth element cations on the surface of silica-derived nanoadsorbents.
Silica (SiO2)-derived nanoadsorbents are a powerful and attractive tool for the extraction and separation of rare earth elements (REE) from many perspectives such as reusability, efficiency and minimum impact on the environment. In the present work, we investigated two different methods of adsorption down to the molecular level: (1) the mechanism of the coordination of different groups of REE (...
