| heal.abstract | A photocatalysis method is described for determining radiation absorbed by a sunlight sensor in liquid form directly exposed to sunlight. The novelty of the method is based on the use of smart packaging materials such as plastic bubbles in which the photocata-lytic solution is placed. During direct exposure (or exposure in a sunlight simulator) of the solution to sunlight, measurements are taken at specific time intervals so that we can estimate the amount of radiation absorbed by our solution at these intervals and correlate this amount with the color change of the solution. Transmittance (photometric) meas-urements of color intensity were made on a flatbed scanner in transmittance mode, the images were saved as JPEG (Joint Photographic Experts Group) files, and the color in-tensity was calculated as the average gray intensity and the color intensity in the RGB color system. The method is simple to perform, creating liquid solutions ( ascorbic acid, metal selenide photocatalyst, methyl-orange indicator ) and mixing them, injecting the solution into a plastic bubble and directly exposing this arrangement to sunlight. On the basis of these data, this method could be used in various applications, such as placement as a hidden or visible photosensor on food or drug packaging. | en |
