摘要

The following conclusions are drawn from the present investigation: 1. The corrosivity of the washer stage for mild steel was maximum followed by those of white water and bleaching section. 2. In the bleaching section, the corrosion inhibition efficiency, evaluated through weight loss study, was found maximum for LH (87.2 %) and was followed in decreasing order by those of PANI (82.3 %), UDH (76.4 %) and ANI (70.9 %). 3. In the white water environment, the corrosion inhibition efficiency, evaluated through weight loss study, was highest for lauric hydrazide (84.9 %) and decreases progressively for undecenoic hydrazide (78.9 %), p-anisidine (74.6 %), and aniline (72.2 %).
