    Abstract: Gaseous reactants usually have complex behaviors ranging from unsteady flow patterns to oscillations due to the differences in various physical and chemical properties. Such behaviors hinder the complete understanding coupled between transport processes and chemical kinetics. Systems within which chemical reactions are coupled with diffusion and co... Show More

    Abstract: The densities of dodecyltrimethylammonium bromide in pure water and in methanol + water mixed solvent media containing (0.10, 0.20, 0.30, and 0.40) volume fractions of methanol were measured at (298.15, 308.15, 318.15, and 323.15) K. The concentrations are varied from (0.4 10-1 to 1.2 10-1) mol kg-1. The results showed almost increase on the dens... Show More

    Abstract: Copper and fluoride ions were removed from wastewater by the coupling of electrocoagulation, fluidized bed and micro-electrolysis (EC/FB/ME) process. The results indicate that the use of aluminum electrode for simultaneous removal of copper and fluoride ions is better than iron electrode. By the orthogonal experiments study of the main factors infl... Show More

    Abstract: Low-cost bare palm branches were prepared as a sorbent for methylene blue dye from aqueous solution. The effect of reaction parameters such as sorbent dose and its particle size, initial dye concentration and the medium temperature were investigated using a batch sorption technique. Additionally, the maximum saturated monolayer sorption capacity of... Show More
