===Measuring absorbance of films in PBA=== | |||
* Soaked PVA-Clay polymer films in 10 ppm PBA and measured absorbance twice ( from two scintillation vials) at each time slot. | |||
** Note that the 10 ppm PBA solution was made by James and Eleni | |||
** During UV-Vis measurements films were removed to avoid further absorption of chemicals. | |||
