Optimisation of glucose templated silica for oil-water separation / Nurul Atiqah Mustaffa, Nur Hafizah Abd Hamid and Siti Nurehan Abd Jalil

In this study, glucose is used as a template to manufacture microporosity in silica. Based on this objective, five different molar ratios of glucose (0%, 10%, 20%, 30% and 50%) were used for this experiment to maximise its affinity to adsorb oil droplets. The sample has been characterized using ther...
