Determination of Metal Contents in Edible Vegetable Oils Produced in Iran Using Microwave-assisted Acid Digestion

The concentration of heavy metals in vegetable oils is an important criterion for the assessment of oil qualities with regard to freshness, keeping properties, storage and their influence on human nutrition and health. Trace heavy metals in vegetable oils are known to have an effect on the rate of oil oxidation. In this work, the contents of lead (Pb), cadmium (Cd), nickel (Ni), manganese (Mn),...

Synthesis and Characterization of Colloidal Nanosilica via an Ultrasound Assisted Route Based on Alkali Leaching of Silica Fume

Colloidal nanosilica is currently being produced by various methods which are mainly high energy intensive and/or not environmentally friendly. It is therefore essential to develop new energy-efficient and environmentally friendly technologies. This paper introduces a new ultrasound assisted route based on alkali leaching of silica fume for synthesis of colloidal silica nanoparticles. The ef...

Elucidation of structural isomers from the homogeneous rhodium-catalyzed isomerization of vegetable oils.

The structural isomers formed by the homogeneous rhodium-catalyzed isomerization of several vegetable oils have been elucidated. A detailed study of the isomerization of the model compound methyl linoleate has been performed to correlate the distribution of conjugated isomers, the reaction kinetics, and the mechanism of the reaction. It has been shown that [RhCl(C8H8)2]2 is a highly efficient a...
