Spectrophotometric determination of vanadium in crude oil

Fractionation and Characterization of Petroleum Asphaltene: Focus on Metalopetroleomics

“…Modern instrumental approaches to determine trace metals and asphaltenes in crude oil is by means of physical methods. Analytical methods were developed for the determination of metals in crude oils and derivatives using various analytical techniques, including flame atomic absorption spectrometry (FAAS) [55], graphite furnace atomic absorption spectrometry (GFAAS) [56], inductively coupled plasma optical-emission spectroscopy (ICP-OES) [57], inductively coupled plasma-mass spectrometry (ICP-MS) [58], X-ray fluorescence spectroscopy [59], spectrophotometry [60], and high-performance liquid chromatography (HPLC) [61]. To date, concentrations of these metals in petroleum have mostly been determined by ICP-OES and ICP-MS because of their distinguished sensitivity, repeatability, and operability [62].…”

Stormwater harvesting for irrigation purposes: An investigation of chemical quality of water recycled in pervious pavement system

“…Vanadium was observed to have a significant correlative relationship with boron, arsenic and fluoride (Fiorentino et al 2007) and have been reported to be the most abundant metallic element present in all crude or residual oils (Mastoi et al 2006, Amorim et al 2007 in the concentration of between 0.1mg/kg -1500 mg/kg (Amorim et al 2007). Results of tests for vanadium concentration in water from the test models were below the mean concentration of 0.01mg/L.…”

A hybrid method combining discharge-assisted laser induced breakdown spectroscopy with wavelet transform for trace elemental analysis in liquid targets

“…Quantitative analysis of liquid oil pollutants is essential for tracing the source of pollutant elements and crucial to the subsequent promulgation and implementation of reasonable prevention and governance measures. Traditional analytical methods, such as atomic absorption spectrometry (AAS), 12,13 inductively coupled plasma optical emission spectroscopy (ICP-OES), 14 Fourier transform infrared spectroscopy (FTIS), 15 spectrophotometric methods, 16 and mass spectrometry (MS), 17 possess high sensitivity in material identification. However, these established indirect analytical methods are unable to avoid highly complex and expensive equipment, as well as a long time for reliable sample preparation.…”
