Biofuel quality control involves the determination of metal and metalloid content. These
species play a very important role because they may modify the efficiency of biofuel …

Simple procedures for the determination of Cr, Ni, Pb and V in gasoline and ethanol fuel by
microwave plasma optical emission spectrometry (MIP OES) are described. Ethanol fuel …

The presence of metallic species in biofuels has increased considerably during the last few
years. The deposition of these species in non-metallic components of automotive engines …

In this study a new method for determination of cadmium in alcohol fuel using Moringa
oleifera seeds as a biosorbent in an on-line preconcentration system coupled to flame …

The presence of Fe (III) can catalyse fuel degradation processes, providing their inefficient
burning and increasing the emission of harmful gases into the atmosphere. Thereby …

An analytical method was developed for the sequential and simultaneous determination of
Pb, Cu and Fe in ethanol fuel samples using high-resolution continuum source …

In this research work, the effect of different concentrations of copper, iron, lead, zinc and
nickel ions on the tendency for gum formation in gasohol fuel is investigated. For that …

This work reports a method for sodium determination in biodiesel fuel by flame atomic
emission spectrometry (FAES) using the dry decomposition for the sample preparation. Two …

In this work it is proposed the one-voltammogram simultaneous determination of Cu (II), Pb
(II), Cd (II), Ni (II), Co (II), and Zn (II) at ppb and sub-ppb levels in bioethanol fuel samples by …

Bioethanol added into gasolines significantly changes the physical and chemical properties
of the resulting fuels and can have a considerable influence on their overall thermo …
