Analysis of peracetic acid solutions
Talanta, 1966In the estimation of peracetic acid in aqueous solution, hydrolysis of the peroxy group must be taken into account. The best volumetric method is an indirect one using cerium(IV) as the oxidant, followed by iodometric titration of the excess of cerium(IV). A spectrophotometric estimation of the hydrogen peroxide present, based on the peroxytitanium(IV)

Silk–Phosphoric Acid Solutions
Nature, 1954NATURAL silk is readily soluble in several solvents, such as cupriethylenediamine, lithium bromide and lithium rhodanide, phosphoric acid, etc. Generally, it is assumed that the dissolution is brought about in such a way that the solvent splits the hydrogen-bonds which intermolecularly connect adjacent fibroin chains, attaches itself to the positions ...

Anion exchange in acetic acid solutions
Analytica Chimica Acta, 1971Abstract The adsorbabilities of 65 elements in water-acetic acid medium on the anionexchanger Dowex 1-X8 have been investigated in the region 2–17.4 M acetic acid. Examples of possible individual separations of elements are given, namely : Cu-Zn, Mn-Cu-Zn, Na-As-Cu and U-Np. A separation of the elements Ag, As, Au, Br. Co, Cu, K, Mn, Mo, Na, Sc and

Wet Oxidation of Salicylic Acid Solutions
Environmental Science & Technology, 2010Salicylic acid is a frequent pollutant in several industrial wastewaters. Uncatalyzed wet air oxidation, which is a promising technique for the treatment of phenolic effluents, has not been analyzed yet for the removal of salicylic acid. The effect of different conditions of pH (1.3-12.3), pressure (1.0-4.1 MPa), temperature (413-443 K), and initial ...

Solutions in difluorophosphoric acid
2011The physical and inorganic chemistry of solutions in difluorophosphoric acid, HPO₂F₂, has been studied, as part of a general study of solutions in non-aqueous protonic solvents. Difluorophosphoric acid is a colourless, associated liquid which might be expected to have solvent properties similar to those of other protonic systems such as H₂O, H₂SO₄ and ...

Extended Matrix Acidizing Using Polymer-Acid Solutions
SPE Technical Symposium of Saudi Arabia Section, 2006Abstract The present work investigates the effect of adding polymer as a retarding agent to acid solutions to slow and control the reaction in matrix acidizing treatment of carbonate rocks. Two different polymers, Polyacrylamide (PAA) and Polysaccharide (Xanthan) and three different acids, hydrochloric acid; acetic acid and formic acid ...

Reactive Solute Transport in Acidic Streams
Water, Air, & Soil Pollution, 1996Spatial and temporal profiles of pH and concentrations of toxic metals in streams affected by acid mine drainage are the result of the interplay of physical and biogeochemical processes. This paper describes a reactive solute transport model that provides a physically and thermodynamically quantitative interpretation of these profiles.
