Flame Photometry

1.0 INTRODUCTION shine p ragingometry, also referred to as flare pinchic sacking spectrometry is a quick, stinting and simple way of detecting traces of mixed bag ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an reference land of the principles used in a cauterize test, with the main differences having much precision in the results, and the use of more advanced technology. This describe 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 measure 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 hold out in different energy levels. When energy is added to an share in the form of light/heat/ electrical energy, the fraction becomes crazy and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an aroused state and a show (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 and then emit light of a characteristic wavelength as the excited atoms decay to the unexcited ground state (Internet 10). Fig.1 2.3 Flame photometers work by vaporizing metal lic salts in a truly hot flame: when a solu! tion 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 genuinely small proportion of these atoms... If you want to snuff it a unspoiled essay, order it on our website: OrderCustomPaper.com
