A method of treating a kaolin particulate material to improve its properties by removal of impurity particles thereform, to improve the brightness, and whiteness and other properties. Method of treating raw kaolin clay for preparing nanoparticles of kaolin clay to replace titanium dioxide in water based coatings, and for use as an adsorbent for the removal of toxic heavy metal ions such as lead, zinc, cadmium, cobalt, copper, and chromium ions from aqueous solutions. A method includes: (a) removing colored impurities by treating pulverized kaolin clay with diluted hydrochloric...

Aqueous solutions of glycols have attracted much attention. These solutions have been used in biochemistry, polymer chemistry and biochemical engineering to separate and purify biological products, biomaterials, proteins, and enzymes from the complex mixtures. The aim of this work is: provide information on the molecular interactions between water, glycols in binary mixtures at different temperatures, to investigate the volumetric and viscometric behaviours of these binary aqueous systems, and correlate the density and viscosity data to the thermodynamics of mixing in terms of Transition...

Experimental densities, were experimentally determined at 298.15 K for the following mixtures: (i) Binary mixtures: Cyclohexane + n-hexane, cyclohexane + n-octane, cyclohexane + n-decane, cyclohexane + n-dodecane, cyclohexane + n- hexadecane, n-hexane + n-octane, n-hexane + n- octane, n-hexane + n-decane, n-hexane + n-dodecane, and n-Hexane + n-hexadecane. (ii) Ternary mixtures: n-hexane + n-octane + cyclohexane, n- hexane + n-decane + cyclohexane, n-hexane + n- dodecane + cyclohexane, n-hexane + n-hexadecane + cyclohexane. (iii) Quaternary mixtures: n-hexane + n-octane + n-dodecane +...
