SM (III) extraction from aqueous solutions by sodium dodecylsulfate

Article preview

Extraction process in Sm 3+ aqueous solutions from nitrate media by sodium dodecylsulfate as collector is investigated. Distribution coefficients on depending of the pH aqueous phase in different concentration of Sm 3+ is obtained.

Study of the corrosion stability of some materials in the titanium (II) and (III) chloride melts

Article preview

The corrosion stability of some pure metals and alloys in the titanium (II) and (III) chloride melts was investigated. It was demonstrated, that the rate and specific features of the process depend upon the chemical composition of metals. Under these conditions chrome-containing alloys are most influenced to the corrosion. Data of the relative corrosion stability of some materials were obtained.

Removal of samarium (3+) and cerium (3+) from nitrate and chloride solutions by ion flotation

Article preview

The ion flotation of cerium (3+) and samarium (3+) from nitrate solutions by use of sodium dodecyl sulphate as a collector with addition of sodium chloride has been stated. The ratio of distribution coefficients and separation coefficient as function of the pH-aqueous phase with different concentration of chloride-ions has been analyzed. The separation coefficient has rise  from 1,3 till 4,75 when chloride has been  added.

Application of center-run extractors in petrochemistry

Article preview

One of the ways of recovery of metals from oil is considered. It is proposed to carry out the extraction of metals from oils using a separator with centrifugal phase separation. This type of separators can be used not only for extraction of valuable components such as metals from oils, but also for purification of water from oil products, as well as for hydrometallurgical production of non-ferrous metals.
