Revised application of copper ion selective electrode (Cu-ISE) in marine waters: A new meta-calibration approach.

Copper (Cu) is a bio-essential trace element that is of concerns due to its potential toxicity at concentrations commonly encountered in coastal waters. Here, we revisit the applicability of Cu(II) ion selective electrode (Cu-ISE) based on a jalpaite membrane for the measurement of Cu in seawater. At high total Cu concentration (>0.
