Sept 17 -Set up for X-Ray and Separation of ionic liquid modified clays
Objective
DescriptionThe exchanged clay was centrifuge for 30 minutes at 4,000 rpm at 4C. The supernatant was collected and stored for future analysis. The remaining clay was washed with water and re-centrifuged for 10 minutes at 4,000 rpm at 4C. The wash process was repeated but with ethanol for the second wash. Two more washes one of water and one of ethanol was repeated by Dr. Hartings. He also air dried the remaining clay on a watch glass overnight. During the centrifuging process it was noticed that the clay separated into two layers (See Figure 1.) It is unclear why this occurred however it is thought the clay might not have been homogenous and therefore parts of it were more homophobic then others.
