Optimization and Comparison of Ni and Cd Removal Using Zinc Powder with the Response Surface Methodology

P. Abbasi; k. Shayesteh; v. vahidfard; M. Hosseini

Volume 17, Issue 4 , October 2020, , Pages 3-20


   In an Iranian zinc smelter plant, nickel and cadmium are removed from the electrolyte solution at the cold purification stage with the help of zinc powder. This study tries to investigate the optimal conditions for the removal of these impurities through the response surface methodology by examining ...  Read More

Demuification of Water-in-Oil Emulsions by Means of Dielectrophoresis

M. Mozafari; A. Ganjizade; .S. N. Ashrafizadeh

Volume 17, Issue 3 , September 2020, , Pages 24-40


  In this work, the demulsification of water-in-crude oil emulsions by dielectrophoresis via applying a non-uniform electric field in a lab-scale cylindrical cell was studied. The stability of emulsions was assessed through monitoring the size distribution of water droplets at 0, 3, 6, and 24 hours after ...  Read More

Optimization of Candida rugosa lipase immobilization parameters on magnetic silica aerogel using adsorption method

Jafarsadegh Moghaddas; Leila Amirkhani; Hoda Jafarizadeh- Malmiri

Volume 13, Issue 3 , July 2016, , Pages 19-31

  Magnetic silica aerogel in hydrophobic and hydrophilic forms were used as support to immobilize Candida rugosa lipase by adsorption method. Response surface methodology (RSM) was employed to study the effects of the three most important immobilization parameters, namely enzyme/support ratio (0.3-0.5, ...  Read More
