摘要：
A convenient and portable smartphone-assisted method for the colorimetric detection of uranyl ions (UO22+) in aqueous solutions is proposed using rifampicin and 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (Br-PADAP) as chromogenic agents. The addition of UO22+ would cause reaction with chromogenic agents to form complexes, changing the colour from orange to dark red in the rifampicin system and from yellow to light pink in the Br-PADAP system. To achieve the on-site estimation of the trace UO22+ concentration range, digital images of colour changes captured by the smartphone under fixed ligh...
