The ZIF-67 with GO worked!! The concentrations of Methylene Blue dropped to almost zero if not zero. This was true for the four concentrations tested, 12.5 ppm, 25, ppm, 50 ppm, 100 ppm.
Now, all the samples are going to be sent to a different lab to analyze the concentration of the ions and the ICP-MS of the solutions.
This week was a rather busy week. It started with creating ZIF-67 so that we can test its efficiency in cleaning Methyl Blue in fresh water solutions. The process started on Friday June, 23. After all of the ZIFs were collected, we remade the control ZIFs with GO Fe3O4 NPs and nonmagnetic GO. In total there are 60 samples
This week we will analyze each sample and see if this truly cleaned out the water as he had hoped. Some of the samples started cleaning the water without being stirred-very promising!
This week in my lab, I FINALLY finished the 132 MB and freshwater samples. UVs were taken from each of the samples and compared. Visually, it was easy to see that the Zn MOFs and Zn MNP were quick to clean up the water. Analytically, it was discovered that all Zr MOFs and MNPs actually absorbed ions and became supersaturated. Co on the other hand, did an excellent job of cleaning the water samples. Yesterday we started the synthesis of a new NP, a Bi-Metallic ZIF. Using Zn, Co, and 2MI, we will create an MNP bonded to graphene oxide (GO). With the results from the UV spectrometer- Zn and Co cleaned the water best- we were able to deduce that a new MNP could be created with Zn and Co as the primary metals. In essence, these NPs should clean the water much better together than just alone. Today, we will continue and finish synthesizing the chemicals and we will leave them in the oven over the weekend to keep the reaction going. Updates and pictures to follow!
