چکیده
This study aimed to investigate the kinetics of anion exchange step ferrous ions with Na-X zeolite in a temperature range 20 and 80°C for period up 8 hours. A sulfate heptahydrate solution was used as ion source sodium zeolite. The results showed change physical appearance progress process. catalyst color observed time changed from yellow brown. exchanged contents increased reached 0.519 at after kinetic model based on Langmuir-Hinshelwood-Hougen-Watson suggested developed describe ion-exchange proposed solved numerically, indicated its ability experimental high correlation coefficients. Finally, activation energy forward reaction 31590.7J/mole compared 28105.5J/mole backward, frequency factors backward reactions were investigated.

The Langmuir-Blodgett (LB) technique is an elegant protocol for the steered assembly of metal nanoparticles, the deposition pressure serving as a convenient parameter to tune the assembly. Adsorption of nanoparticles from the subphase to the air-water interface can provide further control of the process. Citrate-stabilized gold nanoparticles in the aqueous subphase are shown to assemble into ex...
متن کاملBi-Langmuir isotherms' applicability for description of interaction of ion-exchange sorbents with protein mixtures.
The sorption of a protein pair on carboxylic cation exchangers with various contents of ionogenic groups is examined. The bi-Langmuir isotherm calculation is carried out from sorption data for single-component systems. It is shown that good agreement of calculated and experimental data is reached only when protein-sorbent interaction weakens because of implementation of the competitive sorption...
