Abstract : The purpose of this research is to develop a way to appoint the proportion of tungsten in lubricants, hydraulic fluids, using the method of spectral analysis where it reacts tungsten with (5 - (4 - Peredel) Noonan) in the presence of Altheothianat to form a composite (480 nm) (nm 480) The compound consists quickly in the middle of hydrochloric acid and remains constant for at least three hours. It was found under these circumstances that the molecular absorption is (1076 * 10 S 6 dm mol -1 cm -1) At 480 nm and can be applied to the law (Beer) concentrations of tungsten (zero - 20) micrograms / milliliter. Most of the ions located with the tungsten does not interfere in the appointment of the proportion of tungsten, such as Firecracker and that allowed the presence of high concentrations of chloride. Has been applied this method to lubricating oils and hydraulic fluids used in the workshops of Saudi Arabia for the maintenance of aircraft, both of the oils which are not used or used was unloaded from the aircraft. The data obtained covers all the requirements of research, but they differ from what was planned before, was proposed to conduct studies to extract tungsten from Mhaleilh in nitric acid using the isotopes of tungsten radioactive and atomic absorption spectrometry, and some of the difficulties has been modified the study to be in a measure the visible spectrum This was done from the beginning of the search .. It is expected the arrival of radioactive isotopes in the within months, after which conduct studies on the extracts as proposed and g will be attached as an annex to search results once completed.
