Description

Acid Red 73 is a dye that has been used in the treatment of wastewater. It is used as an indicator for the presence of bacterial cells and can be used to estimate their concentration. Acid Red 73 binds to α1-acid glycoprotein, which is found in human serum and other biological samples. The dye adsorbs onto the Zirconium oxide surface when it reaches its optimum concentration, which can be determined by titration calorimetry or electrochemical impedance spectroscopy. The dye may also react with radiation and produce reactive oxygen species (ROS), which may limit its usefulness for radiation sterilization applications.
