What is/are Fluorescent Whitening?

Fluorescent Whitening - In recent years, there was increasing concerns on food safety issues associated with fluorescent whitening agents from package materials. [1] Fluorescent whitening agents (FWAs) are very important chemical additives that are widely applied in the industrial production field. [2] The distribution of sisal fibers in the UHPC matrix was evaluated using the ultraviolet (UV) light and fluorescent whitening agent (FWA). [3] In particular, the ozone oxidation treatment process is applied after SMBR to remove the fluorescent whitening agent, which is a trace pollutant and non-biodegradable.
