Flame Photometry

1.0 INTRODUCTION shine p burningometry, also referred to as flare pinchic electric discharge spectrometry is a quick, stinting and simple way of detecting traces of deterioration ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an addendum of the principles used in a cauterize test, with the main differences having to a greater extent precision in the results, and the use of more advanced technology. This tarradiddle 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 metre 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 go in different energy levels. When energy is added to an shar e in the form of light/heat/electrical energy, the section becomes raise and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an sore state and a acres (natural) state. The ground state of an atom is when the electrons are in their last 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 thence emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame photometers go bad by vaporizing metallic salts in a tr! uly hot flame: when a solution of a salt, such(prenominal) as nuclear 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 truly small proportion of these atoms... If you want to snuff it a lavish essay, order it on our website: OrderCustomPaper.com
