Decomposition of benzene by non-thermal plasma processing: Photocatalyst and ozone effect
Plasma technology has some shortcomings, such as higher energy consumption and byproducts produced in the reaction process. However non-thermal plasma associated with catalyst can resolve these problems. Therefore this kind of technology was paied ...

Modification of thermal and oxidative properties of biodiesel produced from vegetable oils
Trans esterification of three vegetable oils, sunflower oil, linseed oil and mixed oils as; sunflower-soyabean and olein were carried out using methanol, and potasium hydroxide as catalyst. The methyl esters of the corresponding oils were separated ...

Removal of Cr from Synthetic Wastewater by Sorption into Volcanic ash Soil
The possibility of using volcanic ash soils (VAS) or Andisols as a low-cost and natural adsorbent is investigated in this study for the removal of Cr (VI) from synthetic wastewater. Andisols can be used as adsorbent because they are characterized by ...

Utilization and flow of energy in tropical ecosystem: A test case for two Ox-bow lakes
Abstract: To estimate the rate of organic production, two solar powered tropical natural aquatic systems (Ox-bow lakes) have been studied for 24 months. The study of utilization of energy in those two tropical lakes has revealed that herbivores were ...
