Abstract

The inhibiting effect of dithizone (Diphenylthiocarbazone) has been studied regarding the corrosion of 316 stainless steel in 20% w/w HCl at 35C. The effects of the inhibitor have been demonstrated using weight loss measurements. The increase of the inhibitor concentration leads to a decrease in the corrosion rate. This indicates a good adsorbability of dithizone (Diphenylthiocarbazone) on the metal surface. The value of ΔGad s has been calculated and dithizone has the potent to interact with 316 stainless steel through semi-physiosorption and/or semi-chemisorptions.
