“…Several authors reported that the use of temperatures above 70 • C promotes a decrease of the liquid phase viscosity, an increase of the components solubility in the solvent, and microbial growth inhibition [1,5,13]. Despite these advantages, in the present study the temperatures used were 25 and 40 • C because the maximum operating temperature for the Na + resin used was 40 • C, and the range of sugar concentrations studied was low.…”

“…Separation of glucose (G) from fructose (F) [1], sucrose (S) in molasses [2,3] and fructose high-fructose corn syrups [4], represent major challenges in industrial sugar chromatographic separations. As adsorbents, ion exchange resins of sulfonated poly(styrene-co-divinylbenzene) (PS-DVB) have been largely used in the sugar industry due to their chemical inertness, higher capacity and selectivity [5,8]. According to their structure, the resins are classified in two major groups: gel-type and macroporous [9,10].…”

“…Gel-type resins in calcium form are the most used in industrial separation of fructose from glucose due to the strong complexes that these resins form with fructose [1,5,13]. Several authors used calcium resins to fractionate mixtures of fructose, glucose and sucrose [14][15][16].…”

a b s t r a c tAdsorption equilibrium of fructose, glucose and sucrose was evaluated on sulfonated poly(styrene-codivinylbenzene) cation-exchange resins. Two types of resins were used: potassium (K + ) gel-type and sodium (Na + ) macroporous resins. Influence of the cation and effect of the resin structure on adsorption were studied. The adsorption isotherms were determined by the static method in batch mode for monocomponent and multi-component sugar mixtures, at 25 and 40• C, in a range of concentrations between 5 and 250 g L −1 . All adsorption isotherms were fitted by a linear model in this range of concentrations. Sugars were adsorbed in both resins by the following order: fructose > glucose > sucrose. Sucrose was more adsorbed in the Na + macroporous resin, glucose was identically adsorbed, and fructose was more adsorbed in the K + gel-type resin. Data obtained from the adsorption of multi-component mixtures as compared to the mono-component ones showed a competitive effect on the adsorption at 25• C, and a synergetic effect at 40• C. The temperature increase conducted to a decrease on the adsorption capacity for mono-component sugar mixtures, and to an increase for the multi-component mixtures. Based on the selectivity results, K + gel-type resin seems to be the best choice for the separation of fructose, glucose and sucrose, at 25• C.

“…Frontal analysis method [20,21] was used to determine the single component adsorption isotherms of glycine and ammonium chloride. The glycine concentration was in a range between 25 and 180 g/L, and ammonium chloride concentration was between 25 and 200 g/L.…”

Background: Glycine is extensively applied in the field of food, medicine, agrochemistry, etc. It is usually commercially produced by the chemosynthesis method, which generates large amounts of by-product ammonium chloride. Methods: In this paper, the separation of glycine and ammonium chloride was performed with chromatographic column, and deionized water as eluent. The adsorption equilibrium constant K of glycine and ammonium chloride was evaluated by frontal analysis. Based on the equilibrium-dispersive model and a linear driving force of chromatography, the overall mass transfer coefficient k m , axial dispersion coefficient D L , and bed voidage ε t of the column were obtained by moment analysis.
