Dr. Sushma P. Ijardar

I have been awarded M.Phil degree and Ph.D. degree in solution thermodynamics by the Veer Narmad South Gujarat University. After that I have worked on research project entitled “Thermodynamic, acoustic and viscometric behaviour of imidazolium based room temperature ionic liquids in polar organic solvents” funded by Department of Science and Technology (DST), New Delhi under fast track young scientist scheme for 3 years. I joined Central Salt & Marine Chemical Research Institute (CSIR-CSMCRI), Bhavnagar, Gujarat as Scientist in 2011 and worked on study phase equilibria of multi component salt water systems and its applications in recovery of high purity salt from sea water, sub soil brine and saline industrial effluents. I moved to VNSGU as Assistant Professor in Chemistry. I am co-author of 2 book chapters and 36 research papers.
