Effect of hydroxyl and nitrate ions on the sorption of ammonium ions by sulphonic cation exchangers The sorption of ammonium ions and ammonia by the H+ form of sulphonic acid cation exchangers Amberlite 252, Lewatit 2629 and Relite C 360 from a solution containing NH4NO3 in the range of 0 to 0.214 equ/L and NH3 in the range of 0.353 to 0 equ/L was investigated to establish the possibility of their Desalination 175 (2005)
A macroscopic study of the retention capacity of copper by polyaniline coated onto silica gel and natural solid materials Synthesised polyaniline coated onto silica gel and other natural materials such as peanut, almond, nut shells, apricot and olive seeds, etc., have been tested for the ability to retain metallic pollutants. Two adsorbents have been tested, namely silica gel and peanut shells, with copper as the metal Desalination 166 (2004)
Untitled Sorption and pervaporation experiments were carried out with PVA/PAA cross-linked membranes for the separation of azeotropic methyl tert-butyl ether and methanol mixtures. The influence of the PVA/PAA ratio and liquid mixture composition were investigated. With increasing PAA content in the membrane Desalination 160 (2004)
Sorption, diffusion, and pervaporation of benzene/cyclohexane mixtures on silver-Nafion membranes Pervaporation (PV) of benzene (Bz) and cyclohexane (Cx) was performed using Nafion-117 membranes containing silver and sodium ions. The effects of membrane conditioning methods and operating conditions on the permeability and selectivity of PV processing were studied. Membranes treated with NaOH, io Desalination 149 (2002)
Water vapor and gas transport through a poly(butylene terephthalate) poly(ethylene oxide) block copolymer In this paper the transport behavior of water vapor and nitrogen in a poly(butylene terephthalate) poly (ethylene oxide) block copolymer is discussed. This polymer has a high solubility for water (300 cm3 (STP)/cm3 polymer at activity 0.9). A new permeation set up has been built to determine the wat Desalination 148 (2002)
Pervaporation as a deodorization process applied to food industry effluents: recovery and valorisation of aroma compounds from cauliflower blanching water In the food industry, unit operations of stabilisation (such as blanching) produce aqueous effluents generally nonpolluting but often odorous. The objective of this study was to apply the pervaporation process to the deodorization of a cauliflower blanching effluent in order to reduce its volatile o Desalination 148 (2002)
Sorption and diffusion behaviors of water in Nafion 117 membranes with different counter ions The sorption kinetic and equilibrium data obtained at different water activities allowed us to determine the water sorption isotherms and mean diffusion coefficient in the Nafion® membrane. The water sorption isotherm is reminiscent of systems in which there is water clustering at high water activit Desalination 147 (2002)
