Palanikumar Selvapandian; Kanakkan Ananthakumar; Arulsamy Cyril

Volume 2, Issue 2 , December 2015, Pages 143-149

Abstract
  Environmental pollution caused by industrial effluents is an important issue.  Biosorption of crystal violet (CV) from aqueous solution using pearl millet powder (PMP) was investigated in a batch mode. The use of pearl millet powder was as an additional substitution of activated carbon for the adsorption ...  Read More

Negar Amiri; Mojtaba Ahmadi; Meghdad Pirsaheb; Yasser Vasseghian; Pegah Amiri

Volume 2, Issue 2 , December 2015, Pages 156-163

Abstract
  In this study, ozone combination with a sequencing batch reactor was tested in laboratory scale for treating a soft drink wastewater characterized by high concentrations of chemical oxygen demand (COD). A bench scale aerobic sequencing batch reactor (SBR) is carried out by two stages. The system was ...  Read More

Preparation of aldehydic electrospun PAN mats for ammonia removal from wastewater

Golshan Moradi; Farzad Dabirian; Laleh Rajabi; Ali Ashraf Derakhshan

Volume 2, Issue 2 , December 2015, Pages 170-175

Abstract
  Novel electrospun polyacrylonitrile (PAN) nanofiber mats and PAN fabric were chemically modified by dissolved anhydrous stannous chloride diethyl ether saturated with hydrogen chloride to contain aldehyde groups on their surfaces, which are suitable for ammonium adsorption due to their high adsorption ...  Read More

Synthesis of Fe3O4@silica core–shellparticles and their application for removal of copper ions from water

Mohammad Eisapour Chanani; Nader Bahramifar; Habibollah Younesi

Volume 2, Issue 2 , December 2015, Pages 176-182

Abstract
  The main objective of this study was to synthesize an environmentally friendly nano-structural adsorbent. These nano magnetic particles can be applied to remove heavy metal ions from industrial wastewater because the surface of the particles is covered with SiO2, and the SiO2 is inactive and can adsorb ...  Read More

Forecasting Surface Area Fluctuations of Urmia Lake by Image Processing Technique

Javad Ahmadi; Davood Kahforoushan; Esmaeil Fatehifar; Khaled Zoroufchi Benis; Manouchehr Nadjafi

Volume 2, Issue 2 , December 2015, Pages 183-187

Abstract
  Urmia Lake’s water surface area is among the most important parameters needed for water balance analysis. Periodical measurement of this parameter directly by conventional topography almost seems impossible since it is costly and time – consuming. Such limitations highlight the needs for ...  Read More
