Abstract

The present study addresses the use of spectrophotometric analysis to measure the change in absorbance of Hank's balanced salt solution modified with phenol red as a function of immersion time to monitor the corrosion behaviour of Mg. The study confirms the existence of an good correlation between the pH and the absorbance of HBSS measured at any given point of immersion time for up to 1440. min and suggests that absorbance of HBSS at 559. nm can be used as an alternative method to monitor the change in pH of the medium with immersion time.
