General Description:

The National Aeronautics and Aerospace Administration (NASA) missions for space exploration require efficient, self-sustainable water purification systems aimed to provide reliable life support systems. This work focuses on the use of metal doped TiO2 nanoparticles for the photodegradation of urea in urine waste for water recycling systems. Photodegradation studies show that upon irradiation at 340 nm, generated oxidative species react with urea to produce ammonium and nitrates that act as interferences when urea quantification is performed using UV-Vis spectrophotometry. Herein, we report the development of a multivariable model using partial least squares (PLS) regression for the spectrophotometric quantification of urea.
