摘要：
1-phenyl 5-mercarpto 1,2,3,4-tetrazole (PMT) was tested as an inhibitor for the corrosion of steel in 0.5 M H2SO4 and 1/3 M H3PO4 by weight-loss and electrochemical methods. Results obtained showed that the inhibition efficiency of PMT increased with the increase of inhibitor concentration and reached an optimum value (98 per cent) at 10(-3) M in H2SO4 and H3PO4 solutions. The effect of the temperature on the kinetic parameters of corrosion of steel in the aqueous solutions of H2SO4 and H3PO4 with and without addition of PMT has been studied and the associated parameters were determined.
