Objective
1) remade glutaraldehyde films with pdms and glutaraldehyde
2) Clay exchange with CuSO4*5H2O
3) flims with glutaraldehyde and clay .....
- still need make 1 gram PVOH with Gluteraldehyde
- and finish exachange 2,3,4
- finish standards
Description
with glutaraldehyde make sure to wear completely covered goggles on face when handeling
1)
a)
- PVOH=0.5 grams + 5ml of water dissolved on hot plate
- turned off heat no more heat needed added Glutaraldehyde underneath the hood
- let stir underhood with no heat for about 3 minutes
- pured into dish
- let sit underhood
b)
- PVOH~.4 grams + 5ml of water dissolved on hot plate with .1262 g PDMS
- once dissovled turned off heat took under fumehood and added 1 ml of glutaraldehyde with a platic tip pipette
- l let stir without heat underhood for about three minutes
2) Na-MT~.1grams (repeating with 50% and 100% CEC surfactant clay) added to 20ml CuSO4*5H20 underfume hood
- mix for 1 min then dry filter flask it and keep the filtrate
- mix for 5min same thing
- mix for 10min same thing
3)
a)
- Prepare 1.0g PVOH ~ 1.0058g with .1g Na-MT~.1069g heat to dissolve and get a homogeneous mixture
- remove from hot plate and take under fumehood wear goggles, turn off heat and continue stirring
- added glutaraldehyde without heat just stirring for 3 minutes
- pour in dish
b)
- Prepare 1.0g PVOH with .1g 100% CEC Surfactant Clayto dissolve and get a homogeneous mixture
- remove from hot plate and take under fumehood wear goggles, turn off heat and continue stirring
- added glutaraldehyde without heat just stirring for 3 minutes
- pour in dish
Data/observations
1)
a)PVOH=0.5 grams + 5ml of water dissolved on hot plate + 1ml of glutaraldehyde
- clear and rather thick compared to without glutaraldehyde
b)PVOH~.4 grams + 5ml of water dissolved on hot plate with .1262 g PDMS + glutaraldehyde
- clear and rather thick compared to without glutraraldehyde
2) Na-MT~.1grams (repeating with 50% and 100% CEC surfactant clay) added to 20ml CuSO4*5H20 underfume hood
- for Na-MT clay the filter was covered with green/blue color got darker as the time mixed increase, we believe this is because copper exchanged with the na in the clay
- for 100% exchange filler paper was not as green was still pale brown
- for 50% exchange filter paper was not green at all still pale brown
3)
a)Prepare 1.0g PVOH ~ 1.0058g with .1g Na-MT~.1069g heat to dissolve and get a homogeneous mixture + 1ml of glutaraldehyde
b)Prepare 1.0g PVOH with .1g 100% CEC Surfactant Clayto dissolve and get a homogeneous mixture + 1ml of glutaraldehyde
