11/07/2014The samples were once again washed with water, these samples easily precipitated in water, contrary to previous samples. Code names for these samples were NB2_(1-3) To help the precipitation, a little amount of acetone was added, this was also done for sample SB2’s aliquots. The samples were magnetically decanted and dried under vacuum for 4 hours. 15/07/14Samples were taken of pure magnetite, silanized magnetite (NB2) and magnetite coated with silica and silane (SB2_1 and SB2_3) for its characterization in IR for solids. Comparing the spectra given by the IR of the pure magnetite and silanized magnetite (SB2 and NB2) we were able to distinguish a peak at 990.2 cm-1 corresponding to a Si-O bond, confirming the correct silanization of the magnetite, although the amino group couldn’t be identified. Similar results were achieved for samples SB2_1 and SB2_3, however, this peak was not decisive to know if the sample was correctly functionalized giving the fact that the samples are coated with silica. |
