-
(Taylor & Francis Group, 1971-12-01)A general framework for the development of separation science is proposed which links the criterion of merit via an effective transport equation to the molecular basis of separation processes.
-
(Taylor & Francis Group, 1966-01-01)The field of axial and radial dispersion of unsorbed bands in columns or beds packed with spherical particles is reviewed and it is shown that there is broad agreement between various workers: at low reduced velocities ...
-
(Taylor & Francis Group, 1971-08-01)An analysis of static and moving bed perfect column chromatography is carried out for the separation of a binary mixture having constant separation factor isotherms. It is shown that the carrier requirements are identical ...
-
(Taylor & Francis Group, 1972-10-01)In displacement development of mixture of very closely related species on ion exchange columns, determination of the distance between the band middle and the point of initial composition permits an evaluation of HETP. This ...
-
(Taylor & Francis Group, 1966-01-01)The most accurate methods for determining the distribution of radioactivity on thin-layer chromatograms are zonal scanning (1,2) and strip scanning (3). The present communication records the comparison of these two methods ...
-
(Taylor & Francis Group, 1973-12-01)A phenomenological model based on a set of partial differential equations and boundary conditions is proposed for chromatography and, in particular, for gel permeation chromatography. The intractable boundary value problem, ...
-
(Taylor & Francis Group, 1966-01-01)Gel chromatography includes a number of related techniques for separating molecules by means of solvent-swollen gels. The gels consist of three-dimensional networks of cross-linked polymeric chains of controlled porosities ...
-
(Taylor & Francis Group, 1970-12-01)The concentration profiles and the concentration dependent diffusion coefficient, at steady-state liquid permeation, were investigated in plastic films by directly measuring the concentration profile. A stacked film packet ...
-
(Taylor & Francis Group, 1966-01-01)The factors that influence the formation of metal chelate adducts which are of importance in liquid-liquid extraction are evaluated and correlations between the structures and properties of these adducts discussed. A scheme ...
-
(Taylor & Francis Group, 1971-04-01)The calibration of gel permeation chromatograph (GPC) for a given polymer type is usually done by running well-characterized polymer samples of the same type. The available polystyrene and polyglycol standards with molecular ...
-
(Taylor & Francis Group, 1977-12-01)An analysis of the problem of isotope enrichment in species dissolved in aqueous and organic phases is presented. Two examples are given and discussed.
-
(Taylor & Francis Group, 1975-10-01)The adsorption of uranium from a dilute aqueous solution by a large number of inorganic adsorbents has been investigated. A mixture of aluminum hydroxide, ferric hydroxide, and activated carbon in the weight ratio 1:3:4 ...
-
(Taylor & Francis Group, 1970-08-01)All techniques that may be classified at present as “adsorptive bubble separation methods” are described; their relationship to one another is displayed in a schematic diagram which is based on a previous publication.
-
(Taylor & Francis Group, 1974-06-01)Separation of rhenium(VII) from molybdenum, vanadium, chromium, tungsten, iron, cobalt, nickel, copper, manganese, iridium, ruthenium, and uranium is achieved by solvent extraction with 4-methyl-2-pentanol either from ...
-
(Taylor & Francis Group, 1976-01-01)Affinity chromatographic conditions have been developed that allow the separation of chemically modified α-chymotrypsins with reduced esterase activities compared to native α-chymotrypsin. This technique should be useful ...
-
(Taylor & Francis Group, 1971-06-01)Extremely high resolution can be attained with correspondingly long columns made practicable by propelling the carrier gas with a driving force other than inlet pressure.
-
(Taylor & Francis Group, 1968-02-01)The plate-height behavior of open tubular columns, for both gases and liquids, has been studied fundamentally in the turbulent flow region. Appriate analytical expressions have been established on the basis of a purely ...
-
(Taylor & Francis Group, 1975-02-01)The effects of membrane separation parameters using liquid/liquid dialysis under idealized conditions and using hollow fiber geometry were calculated with the aid of a computer. These calculations were carried out for both ...
-
(Taylor & Francis Group, 1967-11-01)For reasons of simplicity the concepts of theoretical plate and transfer unit are frequently used in books and papers dealing with countercurrent separation processes. The physical validity of these two concepts cannot be ...
-
(Taylor & Francis Group, 1967-01-01)A practical method is presented of calculating, with the aid of a digital computer, the positions and shapes of countercurrent distribution patterns of solutes which display concentration-dependent partition coefficients. ...
