Completion of Malachite Green Diffusion through PVA-clay film
At 2294 minutes, the absorbance for the last measurement was taken.
Data analysis was initiated to find the diffusion coefficient for the malachite green.
Film Syntheses
The following weights of the materials were used for the syntheses of films; protocol may be viewed here.
0.11151g clay + 1.00047g PVA
0.11463g clay + 1.00168g PVA
1.00733g PVA
Ion Exchanged Clay
Films cast on lab period 9/26/2014 were observed to be foamy. In addition, granules of the exchanged clay compounds were observed. The film is not homogenized and clay was not thoroughly dispersed.
Second trial in exchanging the ions in the clay made use of choline chloride and tributylhexadecylphosphonium bromide.
The weights of each compound were written on the vial as depicted below the attached picture.
