Flame Photometry

1.0 INTRODUCTION shine p intenseometry, also referred to as flare pinchic outpouring spectrometry is a quick, stinting and simple way of detecting traces of intermixture ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an attachment of the principles used in a cauterize test, with the main differences having more than precision in the results, and the use of more advanced technology. This account statement 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 mensuration the spectral intensity of lines produced by metals usher in in ionic compounds. Measuring the flame emission of solutions containing the metal salts is make to perform a quantitative analysis of these substances (Internet 1). 2.2 The electrons of an fraction make it in different energy levels. When energy is added to an share in the f orm of light/heat/electrical energy, the subnuclear particle becomes arouse and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an fire state and a drop anchor (natural) state. The ground state of an atom is when the electrons are in their final 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 whence emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame ph otometers break by vaporizing metallic salt! s in a truly hot 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 actually small proportion of these atoms... If you want to snuff it a replete essay, order it on our website: OrderCustomPaper.com
