hydrolyzed polyacrylamide/hydrolyzed polyacrylamide in italy
Abstract. The inhibition efficiency (IE) of Polyacrylamide (PAA) in controlling corrosion of carbon steel in ground water in the absence and presence of Zn 2+ has been evaluated by weight loss method. The formulation consisting of 250 ppm PAA and 50 ppm Zn 2+ has 98% IE. It is found that the inhibition efficiency (IE) of PAA increases by the addition of Zn 2+ ion.
The corrosion inhibition of mild steel in 1 M H 2 SO 4 in the presence of polyvinylpyrollidone (PVP) and polyacrylamide (PA) as inhibitors at 30–60°C was studied using gravimetric and gasometric techniques. The inhibition efficiency (1%) increased with increase in concentration of the inhibitors. Increase in temperature increased the corrosion rate in the absence and presence of inhibitors
