WELCOME

Dr. Shafreeza Sobri in the Department of Chemical and Environmental Engineering specializes in the area of electrochemical engineering with an emphasis on metal removal and recovery from wastewater. Her interest ranges from theories related to electrocrystallization of metal to mechanism of crystal growth and nucleation on foreign substrate. As part of her PhD work, she has investigated the feasibility of gold recovery from a thiosulphate-sulphite aged electrolyte used for microelectronics applications. She has successfully developed process design steps for electrolytic flow-by cell which utilizes a three-dimensional electrode for industrial-scale metal-ion recovery. Her work has been published in several journals including Journal of the Electrochemical Society and Electrochimica Acta. She is currently investigating on selective metal recovery for copper, tin and lead from printed circuit board (PCB) wastewater. This involves characterization of the chemical composition of the solution, deposition of metal onto substrate and microscopy imaging of the recovered metals for studies on particle distribution and growth pattern.
