*The course is designed by American University to experiment different aspects of PVOH films.


*During the course PVOH films with different molecular weight will be produced. Effects of cross-linking, addition of different molecules such as gluteraldehyde, different acids, porphrin will be also tested.

Objective

Description

Part 1: Crosslinking of 2 of the films prepared on 14/11/2012

Part 2: Prepare a film

  • 0.5 g PVOH 2200
  • 7 ml of HPLC film
  • 1 ml of porphyrin (conc: 97.42micM)
  • 1 ml of gluteraldehyde
  • 2 drops of HCl

Part 3: AA of the filtrates from 9/11/2012 & 14/11/2012

  • The filtrates had to be diluted.
  • 1 ml of each filtrate was mixed with 10 ml of HPLC water.
  • Calculation(13 ppm of Cu ion was in the stick solution)
  *M(1)*V(1)= M(2)*V(2)
 
  *13ppm*1ml=M(2) *11ml

  *M(2)=1.2 ppm

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.

Notes

This area is for any observations or conclusions that you would like to note.


Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
