My name is Sanaz Raeis-Farshid, I was born in Tehran, Iran, in 1981. I have received B.Sc. degree in Applied Chemistry from University of Tabriz, Tabriz, Iran, in 2003; M.Sc. degree in Applied Chemistry from Azad University of Tabriz, Tabriz, Iran, in 2006; Ph.D. degree in Applied Chemistry from Azad University of North Tehran Branchin 2012.
In 2007, I joined to the Department of Chemistry, Azad University of Lahijan, as a Lecturer, and since February 2009 I am an assistant professor. I work as a reviewer with some ISI journals. My current research interests include water and waste water treatment, synthesis of Nano particles, Nano composites, and Nano Photo-Catalyst, advanced oxidation technology and adsorption by adsorbent, and I have some papers onthese subjects.
I have attended to “2nd International Conference on Multifunctional Hybrid and Nano materials, 6- 10 March 2011, Strasbourg, France- ELSEVIER, and “2nd NANOSMAT-USA 2014, Institute of Nano scale Science& Technology, Rice University, Houston, Texas, USAduring 19-22 May, 2014” as apresenter. Likewise, I won a poster award in “10th Nanotechnology Iranian Student Conference, Rezvan Shahr, Guilan, Iran, August 2011”. I have been invited as guest speaker in “2017 EMN Meeting on Titanium- Oxides(August 8thto 12th, 2017 in Lyon, France)”. Iwas electedas amemberof the Scientific Committee in 2nd Iranian Applied Chemistry Seminar which will be held 27-28 August, 2017 in Zanjan University, Zanjan, Iran.
During recent decades, advanced oxidation processes (AOP) is a common technique in wastewater purification which can effectively handle various hazardous organics in wastewater. Coloured compounds, especially organic dyes, one of the most important pollutants are in the textile industry. Small amount of these substances are created environmental problems. Inrecent years withincreasing production and use of synthetic colours that are more complex structure than the natural colour and chemically very stable, it has been paid more attention to environmental pollution. Textile’s
wastewater consists of these dyes, which many of them are azo compounds that can be satisfactorily removed by semiconductor photocatalysts. Recently, the use of semiconductor photocatalysts has been much noticeable to solve some environmental pollution. Inthe number of various semiconductors, which were used; titanium dioxide (TiO2) was one of the most important photocatalyst for the degradation of environmental contaminants. This is because of its high photocatalytic activity, non-toxicity, chemical stability under different conditions, and relative inexpensiveness. For improving the photocatalytic activity of TiO2, different ideas have been investigated. Doping of metal ions has been usedtoenhancethe photocatalyticactivityof TiO2. The dopantsactaschargeseparators ofphoto induced electron-hole pairs and it is proposed that, after excitation, the electron migrate to the metal where it become trapped and electron-hole recombination is suppressed. The coupling of different semiconductor useful in order to achieve a more efficient electron-hole pair separation under irradiation and accordinglya higherphotocatalytic activity.
