Determination of the Working Exchange Capacity of Weakly Basic Polyacrylic Anionites

Russian Journal of Applied Chemistry, 2005
The nonequilibrium dynamics of sorption of hydrochloric acid by weakly basic polyacrylic anionites was studied. An equation for calculating the working capacity of ion-exchange filters as a function of variable parameters (filtration rate, concentration of the starting solution, and height of the ionite bed in a filter) was derived using the theory of ...

The enthalpies of interaction of strongly basic anionites with amino acid ions

Russian Journal of Physical Chemistry A, 2009
The enthalpies of interaction of strongly basic anionites ARA-1p, AV-17-8, and AV-29-12P with glycine, glutamic acid, and tyrosine anions were determined by microcalorimetry. The interaction of ionites with amino acid anions over the selected concentration range was accompanied by heat release. The value and duration of heat release and the enthalpy of

Equilibrium sorption of sulfuric acid by weakly basic polyacrylic anionites

Russian Journal of Physical Chemistry A, 2007
The sorption of sulfuric acid on Amberlite IRA 67 and (2) Lewatit VP.OC.1072 weakly basic polyacrylic anionites in the free-base form was studied. It was demonstrated that the bisulfate form of the anionites was not produced. In contrast to the sorption of hydrochloric acid, the solution of resinates formed during the sorption of sulfuric acid is ...

[Effect of FAF anionite swelling on its sorption properties].

Prikladnaia biokhimiia i mikrobiologiia, 1982
Experiments were carried out to clarify the effect of swelling coefficients of various samples of the polycondensation anion exchange resin FAF in the C1 form on its sorption properties. The anion exchange resin was used to eliminate contaminating proteins and low molecular weight agents from the allantois fluid and liver cultured cells of pigs ...

[Isolation of the antibiotic hordecin by sorption on anionite AN-15].

Prikladnaia biokhimiia i mikrobiologiia, 1978
It has been shown that Na-salt of hordecine can be selectively adsorbed on anion exchange resin AN-15 and the antibiotic can be then eluated with 96% ethanol acidified with HCl to bring pH to 3.0--3.5. Spectral analysis and testing of the antibiotic activity have demonstrated that hordecine prepared by the above method and that obtained by paper ...

Silica anionite for solid phase extraction: synthesis and optimisation

2017
Solid-phase extraction is used in laboratories in order to concentrate and purify samples for the further use for analysis. For that, a particulate stationary phase or monolith with corresponding functional groups is used together with a mobile phase which contains desired analyte.
