| Abstract: | Chemical means were used to extract polyphenols from healthy brown algae collected in littoral seawater. Experiments on corrosion
of A3 steel, the time-potential curve, and polarization curve in polyphenols seawater showed stronger cathodic polarization compared
with that in common seawater. This indicates that brown algae polyphenols might feasibly be used as corrosion inhibitor in
seawater.
