Tasks for October 22

  • To analyse films in Bisphenol A (BPA)
  • To finish film synthesis from Oct. 17

Completion of film synthesis

Placed film in sodium sulfate, 1% HCl and sodium bicarbonate.

Measuring absorbance of films in BPA

  • Soaked PVA-Clay polymer films in 10.4 ppm BPA and allowed to soak for a determined amount of time ( two scintillation vials for each time slot), after which time films were removed to avoid further absorption of PBA.
