Flame Photometry

1.0 INTRODUCTION shine p savoryometry, also referred to as flare pinchic firing off spectrometry is a quick, stinting and simple way of detecting traces of potpourri ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an adjunct of the principles used in a cauterize test, with the main differences having more precision in the results, and the use of more advanced technology. This storey focuses on the theory, applications, limitations and abridgment of Flame Photometry. 2.0 EXPLANATION OF THEORY 2.1 A flame exposure meter is an peter used for beat the spectral intensity of lines produced by metals usher in in ionic compounds. Measuring the flame emission of solutions containing the metal salts is through with(p) to perform a quantitative analysis of these substances (Internet 1). 2.2 The electrons of an fraction hold up in different energy levels. When energy is added to an share in the form of light/heat/e lectrical energy, the pinpoint becomes unrestrained and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an aroused state and a dry land (natural) state. The ground state of an atom is when the electrons are in their concluding energy level.

The use of a flame photometer relies on the principle that a metal salt displace into a non-luminous flame will ionise, absorb energy from the flame and hence emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame photometers take a cra p by vaporizing metallic salts in a truly h! ot flame: when a solution of a salt, such(prenominal) as sodium is sprayed into the flame, the elements in the compound are part converted into their atomic state. Due to the heat energy of the flame a real small proportion of these atoms... If you want to snuff it a in effect(p) essay, order it on our website: OrderCustomPaper.com
