== | ==Malachite Green Diffusion through PVA-clay film== | ||
* | * I prepared 20 ppm malachite green from a 195 ppm malachite green stock solution provided by Dr. Hartings. | ||
* Using dilution equation, the volume of 195 ppm of malachite green required to make 25 mL of 20 ppm was calculated to be 2.56 mL. | |||
* Using a vernier caliper, the thickness of the PVA-clay film used for diffusion is 0.51 mm. | |||
