Introduction: Cyanide, an environmental pollutant which is found in many different industrial effluents, causes water resources pollution being hazardous to human and environment. Cyanide can be removed from aqueous solutions by different methods but most of them are very expensive. In this study, Lewatit FO36 exchange resin was used to remove Cyanide in a batch system. Methods: Removing the...
salicylic acid-formaldehyde-m-cresol (sfm) terpolymer had been synthesized in dmf media by conventional method. the resulting resin had been characterized by ftir spectra, elemental and thermogravimetric analyses. the morphology of sfm resin had been studied by sem and optical photograph. various parameters like rate of equilibration, effect of ph on ion exchange capacity and effect of concentr...
The removal of the chromium (VI) ion from aqueous solutions with the Lewatit FO36 ion-exchange resin is described at different conditions. The effects of adsorbent dose, initial metal concentration, contact time and pH on the removal of chromium (VI) were investigated. The batch ion exchange process was relatively fast and it reached equilibrium after about 90 min of contact. The ion exchange p...
The effective ion-exchange capacities of ion-exchange materials were determined by measuring the change in the equilibrium conductivity of a column packed with analyte. The developed instrumental method can provide effective ion-exchange capacities for both cation and anion exchangers with simple operations. The cation-exchange capacity of a weak-acid cation-exchange resin (TSKgel SuperIC-Catio...
