New Film synthesis
UV-Vis analysis of MG leftover solutions
<br.> From this, it can be seen that there are two major peaks at 425 nm and 615 nm. <br.> These calibrations curves show that the molar absorptivity at 425 nm is 0.0266 M-1cm-1 and 0.1293 M-1 cm-1 at 615 nm.
<br.> Using Beer-Lambert's Law, the concentrations of leftover dye in solution were calculated:
Determining the amount of MG dye absorbed per mg of filmNote, the results were calculated using 615 nm values
<br.>
