Abstract

This paper is a contribution to correlate benzotriazole (BTA) adsorption films on copper with BTA concentration in bulk solution with hydrochloric (HCl) acid. Three HCl concentrations were tested, 0.001, 0.005, and 0.01 M. Twelve BTA concentrations, from 1 × 10−5 to 1 × 10−1 M, were added to the HCl acid solution at four temperatures from 298 to 328 K. Commercial copper was used. Gravimetric measurements were performed after 3 h experimentation. The Frumkin isotherm gave the best fit to the experimental results. This result was based on the inflection point approach of the isotherm.
