Description
1.25g PVA 1.25g PVA/4 = 0.3125g 0.3125g Bentonite * 97ml solution/3g bentonite = 10.1 mL bentonite solution 55mL solution - 10 mL bentonite solution - 15mL HCL: 30 mL H2O
Data
Percent of PVOH not cross-linked:
NotesBoth activated carbon and 20% beads formed well into many small beads. The cross linking of PVOH films was successful. Only a very small percentage of the films were not cross linked. Beads put in the oven for DSC came out black due to acid left over. This may have cross linked them even more. The DSC analysis does not show glass transition or melting point showing that the beads were successfully cross linked. Further analysis must be done on beads that were not dried in acid to be sure that beads are successfully cross linked. |
