Abstract
The study of the corrosion inhibition of mild steel in sulphuric acid (H2SO4) by the leaf pastes of Sida Acuta was probed using the weight-loss technique. The highest inhibition efficiency of 91.46% with a reduction in corrosion rate from 3.1338mg.cm-2.h-1 to 0.2825mg.cm-2.h-1 was achieved by the addition of the leaf pastes of Sida Acuta at 30g per litre of 1.2M H2SO4. The prediction obtained using the artificial neural network gave the least error and was closer to the experimental corrosion rate value in comparison with the prediction by multiple regression.
