Peach juice as an anti-corrosion inhibitor of mild steel

Ah, the joys of reading the “all article published in the last 7 days”. Without this feed (which is not working properly as at today) I would have completely missed this story by Aprael S Yaro, Anees A Khadom and Hadeel F Ibraheem published in Anti-Corrosion Methods and Materials Volume 58 Issue 3)

Abstract
Purpose
The aim of this paper is to investigate peach juice as a cheap, raw, green and non-toxic anti-corrosion material for mild steel corrosion in hydrochloric acid at different temperatures.
Design/methodology/approach
The corrosion inhibition of mild steel in 1?M HCl solution in the presence of peach juice at temperature range of 30-60°C and concentration range of 5-50?cm3/l was studied using weight loss and polarization techniques. The inhibition effect, adsorption characteristics, mathematical and electrochemical modeling of peach juice were addressed.
Findings
Results show that inhibition efficiency rose with the increase of inhibitor concentration and temperature up to 50°C, while at temperatures above 50°C the values of efficiency decreased. The inhibitor adsorbed physically on metal surface and followed the Langmuir adsorption isotherm. Monolayer formed spontaneously on the metal surface. Maximum inhibition efficiency obtained was about 91 percent at 50°C in the 50?cm3/l inhibitor concentration.
Originality/value
This work is an attempt to find a new, safe to environment, non-toxic corrosion inhibitor. Peach juice is a readily available material in Iraq and Middle East markets.
