Analytical Methodology for the Determination of Trace Metals in Biodiesel
The demand for energy resources by various systems such as production and transportation, as well as for physical comfort continues to grow apace, intensifying global dependence on fossil fuels and their derivatives. For this reason, numerous private and public programs in several countries have established feasible alternatives for the substitution of petroleum derivatives (Sahin, 2011; Saint ́...
متن کاملDetermination of Heavy Metals in Water Samples Using Sodium Sulfide Precipitation and Inorganic Coagulation Followed by Faas Detection
Studies on determination of five heavy metals, i.e. copper (Cu), cadmium (Cd), chromium (Cr), lead (Pb) and nickel (Ni) in water samples collected from drains located outside five factories using sodium sulfide precipitation and aluminium sulphate inorganic coagulation followed by FAAS detection were carried out. The amount of coagulant added, effect of centrifugation time and analysis methods ...
متن کاملMulti-Element Determination of Heavy Metals in Dietary Supplements Using Collision/Reaction Cell ICP-MS Application
Determination of 11 metals (including arsenic, chromium, mercury, iron, copper, nickel, zinc, selenium, lead, cadmium, and thallium) in UK-consumed dietary supplements was carried out using ICP-MS. The instrument used was the Agilent 7500ce, which is equipped with a collision/ reaction cell (Octopole Reaction System), and was operated in no-gas, helium, and hydrogen modes, all acquired within a...
متن کاملDetermination of some trace metals by FAAS after solid-phase extraction with amberlite XAD-1180/TAN chelating resin.
A new chelating resin was synthesized by immobilizing 1-(2-thiazolylazo)-2-naphthol through the -N=N- group on Amberlite XAD-1180. The resin was used for the preconcentration of Cd(II), Co(II), Cu(II), Mn(II), Ni(II), and Pb(II) ions and their determination by flame atomic absorption spectrometry (FAAS). The influences of some analytical parameters, such as the pH, volume of the sample, flow ra...
