Dr. Arif Ahamad is presently working as an Assistant Professor (Department of Environmental Science, Daulatram College, University of Delhi, New Delhi, India). He has obtained his master’s degree from the Department of Environmental Science, Banaras Hindu University (BHU), Varanasi, India in 2011. He obtained his M.Phil. degree in 2014 and doctorate degree in 2019 from the Jawaharlal Nehru University (JNU), New Delhi. The area of his doctoral research is Potentially Toxic Elements (PTEs) in the Groundwater, Soil and Road dust from the Industrial area in Sonbhadra district, Uttar Pradesh, India. He has published more than 10 papers/Book chapters in international and national publishing house in the field of ground water and surface water contamination, wastewater effluent, and landfills as a source of contamination and human health risk assessment. Apart from these several papers are under review. He has also written some editorial articles in popular English newspapers.

Dr. Sharf Elahi Siddiqui has earned his Ph.D. degree in Chemistry from Jamia Millia Islamia University, New Delhi, India in 2019. He has done his Master’s in Chemistry from Department of Chemistry, Aligarh Muslim University in 2011 and MPhil from Department of Chemistry, Kanpur University, Kanpur in 2013. He is particularly interested in the wastewater treatment using advance materials based on the natural plant materials and nanoparticles, and during his PhD, has concentrated upon preparation of multifunctional organic-inorganic nanocomposite having the application properties in the area of photo-catalysis, adsorption, antioxidant and antibacterial. He has developed the lowcost multifunctional material by mixing a low cost and abundant phytogenic plant materials and lower toxic nanoparticles having unique properties. These materials can introduce extraordinary multifunction properties for water treatment having application properties of magnetic separation, photo-catalysis, adsorption and antibacterial properties. He has published several research papers in the peer journals like Journal. He has also published several review papers and book chapters, which cover the recent advancement in the field of water treatment.
