Objective
Description
Part 1: Prepare a film for dye attachment
- 7 ml of sodium bicarbonate
Part 2: Measure the dry mass of cross-linked gluteraldehyde film made on 14/11/2012 and cross-linked on 16/11/2012
mass:0.6707g
Data
AA results
- Actual concentration measured by AA of each filtrates are very close to each other except the number 2(gluteraldhyde filtrate of 30 min). (we stop the measurement too early therefore actual concentration of this filtrate should be ignored)
- AA results supports the UV-vis results from 14/11/1012.
