Fractionation and chemical properties of tear mucoids
Experimental Eye Research, 1971Abstract The physical and chemical properties of glycoproteins in the precorneal tear film that covers the corneal epithelium have never been clearly delineated. Crude mucoid clots were collected from the conjunctival surface of rabbits. Three types of glycoprotein were fractionated by gel filtration on Sephadex G-150 using tear mucoid.

Chemical Fractionation of Phosphorus in Stabilized Biosolids
Journal of Environmental Quality, 2008Three chemicals—ferrous sulfate (FeSul), calcium oxide (CaO), and aluminum sulfate (alum)—were applied at different rates to stabilize P in fresh, anaerobically digested biosolids (FBS) obtained from an activated sewage treatment plant. A modified Hedley fractionation procedure was used to assess P forms in these sludge‐borne materials and in a ...

Inactivation of Brucellaphages by Chemical Fractions of Brucella
Nature, 1965IN order to examine the inactivation of phages the following Brucella substrates were used: (a) Acetone-killed bacteria of Brucella melitensis strain 16 M, suis 1330 and abortus strain 12, according to Olitzki1; (b) protein, polysaccharide and nucleoprotein fractions of Brucella melitensis strain 16 M obtained by extraction with phenol-water, according

Isotopic fractionation – chemical v. environmental perspective
Environmental Chemistry, 2012In recent years, we have witnessed an enormous increase in applications of quantitative isotopic measurements that have contributed to solving problems related to chemical pollution. Some fundamental concepts have been laid out in an excellent introduction on this developing technique.

Critical Aspects of Sedimentary Phosphorus Chemical Fractionation
Journal of Environmental Quality, 1994AbstractSequential leaching procedures have been widely used as an environmental tool to quantify sedimentary P reservoirs. Nevertheless, they still present important issues that need to be investigated such as readsorption of leached ions and organic P hydrolysis.

The Fractionation of Copolymers by Chemical Composition
Journal of Macromolecular Science: Part A - Chemistry, 1968Abstract Phase diagrams for the system of methyl ethyl ketone, cyclo-hexane, and styrene-acrylonitrile copolymer were determined. The phase diagrams indicate that the copolymer may be fractionated by chemical composition in this system. Discussions of the thermodynamics are also presented, to show that copolymers can effectively be fractionated into ...

Chemical fractionation of uranium isotopes
Journal of Inorganic and Nuclear Chemistry, 1969Abstract Precise measurements were made of the chemical fractionation of uranium-235 and uranium-238 between several forms of U(IV) and U(VI) salts. The observed separation factors were very much smaller than previously supposed. It is shown that the chemical exchange method of isotope separation is unlikely to be economically or technically useful.
