TiO2-SiO2/chitosan nanocomposite was synthesized using simple sonochemical technique. The characteristics of the synthesized nanocomposite were examined by TEM, SEM and EDX analysis. The performance of the prepared TiO2-SiO2/chitosan nanocomposite as efficient sonocatalyst was investigated for the degradation of methyl red. Sonocatalytic degradation o...
Biodiesel combustion in diesel engines is associated with reduced carbon monoxide, particulate matter and unburned hydrocarbons emissions, but several concerns remain including deposition, low thermal efficiency elevated nitrogen oxides production. To this end, the incorporation of gasoline additive has been proposed as a solution to drawbacks posed by biodiesel. Integrated chemical kinetics-co...
Introduction: Due to the widespread use of toxic chemicals in most workplaces that can lead to toxic effects on human, various chemical extraction technique have been defined for analysis these toxic substances in air, water and biological samples. The purpose of this research is extraction of toluene and methyl ethyl ketone from aquatic samples with needle trap device and one co...
Background and Aims:Nowadays, many different techniques to extraction of chemical compounds from aquatic samples have been introduced, for examples techniques based on the use of needles that were packed with some sorbents. Considering that so far no synthesis sorbent based on single-walled carbon nanotubes and sol-gel techniques for the extraction of toluene and methyl ethyl ketone from ...
