Abstract Considering from a point of view of the recycling of resources that melting fly ash produced by melting the fly ash and incineration residue discharged from incinerators of municipal refuse is useful resources of concentrated heavy metals, this paper presents acid extraction processes developed for using the useful heavy metals and salts ...

Extraction of Mineral Acids with Neutral Organophosphorus Extractants
Radiochemistry, 2001Extraction of HNO3, HCl, H2SO4, H3PO4, H3AsO4, HF, and H2C2O4 with triisoamyl phosphate (TiAP), diisooctyl methylphosphonate (DiOMP), isoamyldialkyl(C7-C9)phosphine oxide (DRPO), and cyclohexyldialkyl(C7-C9)phosphine oxide (DRPO-1Ts) was studied, and the extraction isotherms were obtained.

Extraction of Lactic Acid by Means of a Mixed Extractant
Industrial & Engineering Chemistry Research, 2001Equilibrium studies on the extraction of lactic acid by means of a mixed extractant (a mixture of tri-n-octylamine and Aliquat 336 in decanol) are carried out. Different ratios between the two extractants are investigated, and the obtained results are compared with those using the individual extractants.

The utility of DNA-or RNA-based testing depends, in large part, on the quality and nature of the diagnostic sample. A variety of methods is available to extract nucleic acids for analysis. The choice of technique should consider both the sample source and the nature of the eventual assay.

Solvent Extraction Studies of Holmium with Acidic Extractants
Separation Science and Technology, 1993Abstract Liquid-liquid extraction studies of holmium with 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester, naphthenic, and Versatic 10 acids have been carried out. The nature of the extracted species and the extraction equilibrium constants of these systems have been determined from aqueous nitrate solution.

Deproteinization of cell extract with silicic acid
Archives of Biochemistry and Biophysics, 1968Abstract A new method of deproteinization of cell extract is described. This method uses silicic acid (SA) as an adsorbant. The cell extract is suspended in either phosphate or Tris buffer (pH 6.2–7.8) with 0.3 m NaCl. A single passage through the SA column removes 95–99% of the protein from the extract, while 100% of the soluble RNA, 90% of the ...

Extraction of Amino Acid with Organophosphorus Extractant
1992ABSTRACT Extraction of amino acids and their related compounds with di(2-ethylhexyl)-phosphoric acid(D2EHPA) dissolved in benzene was studied. Distribution ratio of amino acid D was proportional to the fraction of amino acid in the form of zwitterion.

Solvent extraction of transfer ribonucleic acids
Analytical Biochemistry, 1970Abstract Mixed tRNA's from E. coli are selectively extracted from an aqueous solution containing 0.05 M Tris-HCl, 0.01 M MgCl2, and various concentrations of NaCl with an organic solution containing Adogen 464, a tetraalkylammonium chloride, in Freon 214.

Concentrating Nucleic Acids by Extraction with Butanol
Cold Spring Harbor Protocols, 2017During extraction of aqueous solutions with solvents such as secondary butyl alcohol (isobutanol) or n-butyl alcohol (n-butanol), a proportion of the water molecules is partitioned into the organic phase. Nucleic acids remain in the aqueous phase.

Dissimilation of Citric Acid by Bacterial Extracts
Nature, 1953Aerobacter aerogenes is able to utilize citric acid as sole source of carbon for growth, and from an analysis of fermentation liquors, Deffner and Franke1 and Brewer and Werkman2 concluded that citrate is dissimilated to oxaloacetate and acetate as initial products.
