چکیده
Electrodialysis is a technique based on the transport of ions through selective membranes under the influence of an electrical field. Separation of ammonium sulfate by electrodialysis (ED) was modeled based on experimental data. The model was developed by use of a differential equation of mass balance by regarding the time. Neglecting resistances of ion-exchange membranes compared with resistances of bulk solutions in dilute and concentrate compartments and substituting a relation for solution resistance as a function of concentration, the final one-parameter model was obtained. The model parameter was determined by the experimental data. This model gives the time required to get a desired concentration in the dilute compartment for various voltages and flow rates. To validate the model, the predicted data were compared with experimental dataکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
