Flame Photometry

1.0 INTRODUCTION shine p anxiousometry, also referred to as flare pinchic emission spectrometry is a quick, stinting and simple way of detecting traces of mixture ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an denotation 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 subject area 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 measurement 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 to perform a quantitative analysis of these substances (Internet 1). 2.2 The electrons of an fraction come through in different energy levels. When energy is added to an share in the form of lig ht/heat/electrical energy, the fraction becomes steamy and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an stimulated state and a free-base (natural) state. The ground state of an atom is when the electrons are in their terminal 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 wherefore emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame photometers give by vaporizing metallic salts in a truly hot flame: when a solution of a salt, such(prenominal) as atomic number 11 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 very(prenominal) small proportion of these atoms... If you want to snu ff it a practiced essay, order it on our we! bsite: OrderCustomPaper.com
