Physicochemical aspects of in situ surfactant washing of oil contaminated soils,nts and their blends was tested on small columns. The kinetics of oil displacement and surfactant sorption-desorption were studied. Further, the viscosity behavior of emulsions of varying compositions was investigated. No single optimum HLB value was found for the displacement of a selected oil. It

X-ray microscopy studies of aqueous colloid systems, to visible light. Up to now, the smallest structures that can be visualized are about 30 nm in size. It is possible to image objects directly in their aqueous environment without preparational procedures like drying, staining, etc. In the wavelength range of 2.4 nm ⩽ . ⩽ 4.5 nm water absorbs x-radi

Competitive and displacement adsorption of cetylpyridinium chloride and p-nitrophenol on charged suhloride (CPC) and p-nitrophenol (PNP) on charged silver micro particle surfaces. The investigations have shown that this surface spectroscopy is an extremely powerful technique for monitoring the interfacial behavior of CPC and PNP, for assessing adsorbate orientation, displacement kinetics, competi
