In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...
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...
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 conc...
In this study, graphene Th(IV) phosphate was prepared by sol-gel precipitation method. The ion-exchange behavior of this cation-exchanger was studied by investigating properties like ion-exchange capacity for various metal ions, the effect of eluent concentration, elution behavior, and thermal effect on ion-exchange capacity (IEC). Several physicochemical properties as Fourier transform infrare...
Proton exchange membranes for fuel cells were synthesized from the blend of copolymers of vinyl acetate-acrylic ester and styrene-acrylic ester, which were modified by sulfonation and addition of silica gel. Water uptake, ion exchange capacity, infrared spectroscopy and tensile tests were applied to characterize the prepared membranes. The results show that the prepared membranes with the proce...
In the present work, the effect of bed expansion on BSA adsorption on Amberlite IRA 410 ion-exchange resin was studied. The hydrodynamic behavior of an expanded bed adsorption column on effects of the biomolecules and salt addition and temperature were studied to optimize the conditions for BSA recovery on ion-exchange resin. Residence time distribution showed that HEPT, axial dispersion and th...
In this research paper in air synthesis of Psyllium and zirconium(IV)tungstoiodophosphate based organo-inorganic hybrid ion exchanger has been reported. Synthesised hybrid ion exchanger has been characterized by FT-IR, SEM, EDS and TGA/DTA/DTG and chemical composition. Ion exchange capacity and thermal studies of the synthesised ion exchanger were investigated using the potassium chloride solut...
Background: In this study we have prepared the IgA solution from normal human plasma using plasma fractionation and ion exchange chromatography. Materials and Methods: Using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction III was prepared as a suitable source for IgA preparation. Then it was treated with caprylic acid for separation of impurities. For enrichm...
جداسازی و تلخیص آنزیم لیزوزیم از سفیده تخم مرغ و بررسی برخی اثرات باکتریولیتیک آن درمحیط کشت .آنزیم لیزوزیم طی مراحل مختلف به روش کروماتوگر تبادل یونی ion exchange chromatography از سفیده تخم مرغ تهیه و خالص گردید. فعالیت لیزوزیم تهیه شده با افزودن آن به سوسپانسیونی از باکتری میکروکوکوس و اندازه گیری تغییرات جذب نور توسط اسپکتروفتومتر مورد ارزیابی قرار گرفت . باتزریق لیزوزیم تجارتی طی چند مرحله...
