Literature ReviewOpen accessAll words, across the recordOptimizing the Surface-Active Performances of Cat-Anionic Mixtures: A Short ReviewCamillo A. La MesaMixtures of oppositely charged surfactants are used for applications requiring extensive foaming. This holds true for cat-anionic systems. Their bulk behavior is known in detail, when surface, or interface, properties do not attract the same attention. The thermodynamic features of such systems and the strategies interrelating the behavior in bulk to that at surfaces are outlined. Such systems are strongly … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 4 Nov 2023 · 4,931 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRemoval and Recovery of Lead from Aqueous Solution by Low Cost MediaLucia Pappalardo, Fawwaz Jumean, Naser AbdoProblem statement: To remove Pb(II) from wastewater using local UAE sand and then to recover the removed Pb(II). Approach: Removal efficiency of Pb(II) from wastewater was investigated using white, yellow and red United Arab Emirates sand with pore sizes < 300 μm. Two methods were employed: batch equilibrium and column filtration. In the batch equilibrium study, the effect of sand … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 6,911 accessesView PDFCite
