DETERMINATION OF SODIUM, POTASSIUM, CALCIUM AND LITHIUM IN A WHEAT GRASS BY FLAME PHOTOMETRY K. V. Shah*, P. K. Kapupara, T. R. Desai R. K. College Of Pharmacy, Kasturbadham, Rajkot, Gujarat, India-360 003. ABSTRACT Wheat grass is well known and easily available plant and being used for treatment of various diseases since many decades.
Photoelectric flame photometry, a branch of atomic spectroscopy is used for inorganic chemical analysis for determining the concentration of certain metal ions such as sodium, potassium, lithium, calcium, Cesium, etc. In flame photometry the species (metal ions) used in .
In this article we will discuss about the estimation of phosphorus and potassium for analysing soil. Estimation of Available Phosphorus: i. Olson's Method: Principle: Available phosphorus is extracted from soil with N/2 sodium bicarbonate with pH adjusted to 8.5. By adding molybdate and stannous chloride solution a blue colour develops and this is read on [.]
Flame photometry, more precisely called flame atomic emission spectrometry or "flame photometry" is a traditional instrumental analysis method. It is originated a long back to Bunsen's flame-color tests for the qualitative identification of some selected metallic elements.
Quantification of the amount of NA, K and Cl from plant leaves. ... was used for the estimation of mineral ions content. Calcium, potassium and sodium were determined photometrically by the flame ...
THE DETERMINATION OF CALCIUM IN BIOLOGICAL FLUIDS BY FLAME PHOTOMETRY BY F. J. N. POWELL Frotm the Pathology Unzit, St. James's Hospital, Leeds (RECEIVED FOR PUBLICATION MARCH 18, 1953) The use of flame photometers has greatly simplified and expedited the estimation of sodium and potassium. Calcium is one of the elements
A simple flow injection with flame photometric detection has been developed for determination of sodium, potassium, and total alkalies in portland cement, fly ash, admixtures, and water of concrete. A liquid sample or a digest of solid sample was injected into a water carrier stream which flowed to a flame photometer. A change in emission intensity at a selected wavelength was recorded as a peak.
It is also known as flame emission spectroscopy. Currently, it has become a necessary tool in the field of analytical chemistry. Flame photometer can be used to determine the concentration of certain metal ions like sodium, potassium, lithium, calcium and cesium etc. In flame photometer spectra the metal ions are used in the form of atoms.
1945) many attempts have been madeto estimate calcium; unsuccessful data remain unpublished, and hitherto reported methods are inaccurate or tedious. In one of the earliest reports in this field Belke and Dierkesmann (1948) attempted the estimation using a flame photometer equipped with acetylene gas anda green filter reputedly notabsorbingcom-
Determination of Calcium, Magnesium, Sodium, and Potassium in Foodstuffs by Using a Microsampling Flame Atomic Absorption Spectrometric Method After Closed-Vessel Microwave Digestion: Method ...
Flame Photometer, Corning Flame, Photometry. Note: calcium is measured by using the calcium hydroxide band emission at 622 nm. However, the main atomic emission occurs at 423 nm. The other elements of group I and II in the periodic table also give a characteristic and sometimes intense band of emitted radiation when introduced into a flame (see Table below). However, if these are to be ...
An acid extraction procedure will enable direct measurements of calcium in DNA and DNP, or a standard addition technique is used at higher concentrations. Procedure Deionised distilled water is used throughout. Glassware is acid cleaned and rinsed thoroughly in deionised water prior to use to avoid contamination. Acid Extraction

Spectrophotometric Estimation of Calcium ... the available methods are very unselective. . To estimate small amounts of Ca (II), it is thus often preferable to use micro volumetric estimations, spectrography, or flame photometry. With ammonium purpurate. (Muroxide)
Flame Photometer Range: The estimation of the Alkali metals by Flame Photometry (e.g. Sodium determination in Foods, Sodium and Potassium determination in Cement), is by far the most important application of Flame Photometers in routine chemical analysis.
A photoelectric flame photometer is a device used in inorganic chemical analysis to determine the concentration of certain metal ions, among them sodium, potassium, lithium, and calcium.Group 1 and Group 2 metals are quite sensitive to Flame Photometry due to their low excitation energies.
Determination of sodium and potassium by flame photometry 04.09.12 ... 3.1 Preparation of standard solutions Standard solutions are prepared by dilution of stock solutions. Use different glass pipettes and numbered ... Determination of sodium and potassium by flame photometry 04.09.12
Determination of calcium and magnesium in plant material, by absorption flame photometry . Ondino Cleante Bataglia 2; J. Romano Gallo 2. ... A method for determination of calcium and magnesium by absorption flame photometry was studied using a Perkin-Elmer model 303 spectrophotometer equiped with digital concentration readout model DCR1.
Results on plasma were consistently 2% higher by flame photometry than by EDTA titration. Other methods of calcium determination, depending on the use of radiation buffers or standard addition, were found to be unsatisfactory because of variable interference by phosphate at different calcium levels.
Flame photometry is a simple, relatively inexpensive, high sample throughput method used for clinical, biological, and environmental analysis. The low temperature of the natural gas and air flame, compared to other excitation methods such as arcs, sparks, and rare gas plasmas, limit the method to .
PRACTICAL 2: DETERMINATION OF SODIUM AND POTASSIUM ION CONCENTRATIONS 2.1 Introduction ... The flame photometer ... you will calibrate a flame photometer using standard sodium and potassium solutions then measure the Na+ and K+ .
A Guide to Single Channel Flame Photometer Analysis Brief History As a direct result of the work done by Kirchhoff and Bunsen in the early 1860's, the possibility of using the characteristic radiation emitted by atoms excited in flames for quantitative analysis was realised.
Sep 01, 2019· Flame Photometry: Its Principle, Instrumentation & Applications. Flame photometry is a process wherein the emission of radiation by neutral atoms is measured. The neutral atoms are obtained by introduction of the sample into flame. Hence the name flame photometry. Since radiation is emitted, it is also called as flame emission spectroscopy.
