To evaluate the effect of synthesised calixarenes as new inhibitors on the corrosion of steel in HCl media at various temperatures.
Abstract
Purpose
To evaluate the effect of synthesised calixarenes as new inhibitors on the corrosion of steel in HCl media at various temperatures.
Design/methodology/approach
Calixarenes have been synthesised and tested as corrosion inhibitors. Gravimetric technique and potentiodynamic polarisation and impedance spectroscopy methods were used.
Findings
Calixarenes exhibited a good inhibition. Their efficiency decreases slightly with temperature.
Research limitations/implications
It was found that the inhibition efficiency increases with the concentration of inhibitors to reach 92 per cent at 10−4M.
Practical implications
The efficiency of calixarene derivatives increases with the concentration and falls slowly with temperature to attain 84 per cent at 353 K range. Calixarenes can be used in chemical cleaning and pickling processes.
Originality/value
The originality of this work is to find an inhibitor to give protection close to 100 per cent.
