Determination of titanium in aircraft lubricating oils by atomic absorption spectrophotometry

Direct determination of metals in lubricating oils by laser ablation coupled to inductively coupled plasma time-of-flight mass spectrometry

“…The methodology used for the analysis of oil samples should be rapid and capable of determining several elements simultaneously. Among the most common techniques employed are the rotating-disk electrode spark optical emission spectrometry (RDE-OES), [2][3][4] atomic absorption spectrometry (AAS), [5][6][7] optical emission spectrometry (ICP-OES) [8][9][10][11][12] as well as mass spectrometry (ICP-MS) with inductively coupled plasmas [13][14][15] and X-ray fluorescence spectrometry (XRF). 16,17 For a long time RDE-OES was the method of choice because of its high sample throughput and capabilities of simultaneous multielemental determinations.…”

Inductively coupled plasma--atomic emission spectrometry: trace elements in oil matrices

“…It is presumed that the acid dissolves at least a portion of the particles. In a procedure developed In a recently reported atomic absorption procedure for determining titanium in aircraft lubricating oils, a small amount of an acid mixture (HF/HCl) was added to an MIBKdiluted oil sample, after which the sample was shaken for 10 s and then analyzed (55). Analytical results obtained for several used aircraft lubricating oil samples by this atomic absorption method with both titanium powder (325 mesh) and…”

Hydrogen peroxide photometric analysis of titanium in vanadium alloy

“…The determination method of titanium includes FAAS method [2], GFAAS method [3], ICP-AES method [4], indirect AAS method [5], derivative spectrophotometry [6], hydrogen peroxide-photometric method [7], alternating current voltammetry method [8], gravimetric method [9], titration method [10] and etc.. In the above methods, the hydrogen peroxide photometric method was widely used in determination of titanium in various metal or alloy materials, which had advantages of being fast, accurate, cheap and easy to operate.…”
