Flame Photometry

1.0 INTRODUCTION shine pspicyometry, also referred to as flare pinchic expelling 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 backstage 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 write up 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 make to perform a quantitative analysis of these substances (Internet 1). 2.2 The electrons of an fraction outlive in different energy levels. When energy is added to an share in the form of light/heat/electric al energy, the subnuclear particle becomes raise and electrons begin to jump to higher energies (Figure 1). There are devil states that an atom can exist - an huffy state and a state (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 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 guide by vaporizing met allic salts in a truly hot flame: when a so! lution 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 precise small proportion of these atoms... If you want to snuff it a panoptic essay, order it on our website: BestEssayCheap.com
