Spectrophotometric determination of titanium with o-carboxyphenylfluorone in cationic micellar media, and its equilibrium and kinetic studies

Spectrophotometric Determination of Titanium (Iv) in Steel, Paint and a Cosmetic Cream Using Tannic Acid in Micellar Medium

“…Spectrophotometric methods occupy special position in titanium determination due to their simplicity, less expensive instrumentation and high sensitivity. A number of chromogenic reagents are reported for the determination of titanium (IV) such as, 2, 4-Dihydroxyacetophenoneisonicotinoylhydrazone by forming a red coloured complex, Reddy, et al (2015), 5-Bromo-2hydroxy-3-methoxy benzaldehyde-p-hydroxybenzoic-hydrazone by forming an orange coloured soluble complex at λmax = 390 nm , Devireddy, et al (2014), [o-carboxyphenylfluorone] in the presence of hexadecyltrimethyl ammonium chloride , Hoshino, et al (2011) and resacetophenone p-hydroxybenzoylhydrazone in presence of Triton X-100 , Varghese, et al (2006). Titanium (IV) also, determined by the formation of a yellowish-orange ternary complex with thiocyanate (SCN − ) and cetyltrimethyl ammonium bromide, Tarafder and Thakur, (2008), and by using N'-(2hydroxybenzylidene)-3-oxobutanehydrazide as a reagent forming a reddish orange colored complex at 500 nm, Srilalitha, et al (2010).…”

Simple and Rapid Spectrophotometric Determination of Titanium on Etched Aluminum Foils

“…Various analytical techniques, including neutron activation analysis (NAA) [12], graphite furnace atomic absorption spectrometry (GFAAS) [13], inductively coupled plasma-atomic emission spectrometry (ICP-AES) [14], inductively coupled plasma-mass spectrometry (ICP-MS) [15], X-ray fluorescence (XRF) [16], catalytic adsorptive stripping voltammetry (CASV) [17] and X. F. Du ET AL. 150 spectrophotometry [18][19][20][21][22][23], were used for the determination of Ti (IV) in different types of matrices. Although NAA, GFAAS, ICP-AES, ICP-MS and XRF can determine simultaneously major & trace elements and the combination is considered to have several advantages over the separate technique, spectrophotometry continues to offer the best alternative for routine analysis of Ti (IV) in the absence of these expensive instruments, due to its common availability, simple procedure, high accuracy and low cost effectiveness.…”

“…During the spectrophotometric determination of Ti (IV), a number of organic chromogenic reagents, such as o-carboxyphenylfluorone [19], ponceau S [18], diantipyrylmethane [20], resacetophenone p-hydroxybenzoylhydrazone [24], thiocyanate [25], 2,3-dihydroxynaphthalene [26], 3,5,7,2',4'-penta hydroxy flavone [27], 5-(2', 4'-dimethylphenylazo)-6-hydroxypyrimidine-2,4-dione [28], bromopyrogallol red [29] and o-chlorophenylfluorone [30], have been used to produce an intense color for absorbance measurement. Most of these reagents are expensive, harder-to-obtain and environmental-unfriendly.…”

Study of the Catalytic Effects of Trace Titanium on Oxidation of Pyronin B with Hydrogen Peroxide and its Application

“…Numerous methods were reported in the literature for the determination of titanium(IV) in trace levels include spectrophotometry [2], high performance liquid chromatography [3], atomic absorption spectrophotometry [4], inductively coupled plasma (ICP) atomic emission spectrometry [5], ICP-optical emission spectrometry [6], ICP-mass spectrometry [7], flow injection chemiluminesence [8], electrochemical method [9,10], neutron activation analysis [11]. However, some of them are either insensitivity enough or time consuming or requiring complicated and expensive equipments.…”
