Abstract

Solubility isotherms of water - Syntamide-5 (or Syntamide-5K) - ammonium chloride (or boric acid); water - syntanol (or catamine AB) - boric acid, water - sulphonol (or sodium dodecyl sulfate) - hydrochloric (or sulfuric acid), water - neonol AF-9-12 or neonol AF 9-25 - a salting-out agent, water - sodium dodecyl sulfate - acid systems were built. Regions of liquid two-phase equilibrium, suitable for the use in the extraction, were detected. The interfacial distribution of a number of metal ions in the presence of other additional complexing reagents: acetylacetone in the water - oksifos B - ammonium sulfate and thiocyanate ions in the water - catamine AB - potassium chloride, diantipyrylalkanes in water - sodium dodecyl sulfate (or sulphonol) - acid - salt systems were studied. A number of methods of extraction-photometric determination of elements were developed. The effect of catamine AB on the complexation of metal ions with organic reagents was investigated. The solubility in sulfate (chloride, nitrate) ammonium - potassium bis(alkilpolioksietilen)phosphate (oksifos B) - water and water - syntanol - magnesium salt systems in a wide temperature range was studied. The possibility of claud point extraction in the researched systems was established.
