- Abstract
A kind of acid inhibitor-Guanidine acetic acid chitosan (GAAC) has been synthesized by 1-chloro guanidine acetate and self-made chitosan. Effect of inhibitor on N80 steel is measured by weight-loss method and its adsorption mode is derived by amplitude circuit spectrum. Experimental results indicate its behavior of adsorption conforms to Langmuir mono-layer mode and its adsorption enthalpy is obtained subsequently. This article also adopts GC-MS to study the disciplinarian of degradation in acid solutions and analyze its mechanism of sustainably long-term inhibitory function.
