At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to advancing the science behind material protection. Our latest research delves into the effectiveness of organophosphorus derivatives, specifically a compound we've designated DAMP, as a superior corrosion inhibitor for copper in aggressive acidic environments like hydrochloric and sulfuric acid solutions. This exploration is crucial for industries dealing with metal processing, chemical manufacturing, and infrastructure maintenance where copper components are exposed to corrosive agents.

Our extensive studies, employing techniques such as weight loss measurements and electrochemical methods, have confirmed that DAMP significantly reduces copper corrosion. We've observed that as the concentration of DAMP increases, the corrosion rate decreases substantially. This efficacy is particularly notable at optimal concentrations, where the inhibition efficiency reaches impressive levels. Understanding the precise mechanism behind this protection is paramount. Our electrochemical study of copper corrosion and subsequent analysis revealed that DAMP functions by adsorbing onto the copper surface. This adsorption is facilitated by the presence of heteroatoms (nitrogen, oxygen, and phosphorus) within the DAMP molecule, which have a strong affinity for the metal surface. This leads to the formation of a dense, protective film that acts as a barrier, preventing corrosive species from reaching the copper.

Further insights were gained through advanced surface analysis techniques. SEM EDX analysis of copper corrosion showed a marked reduction in surface damage and the absence of corrosion by-products when DAMP was present, compared to untreated copper samples. The FT-IR spectra confirmed the adsorption of DAMP molecules onto the copper surface, highlighting the interaction via its functional groups. Moreover, our quantum chemical study of corrosion inhibitors provided theoretical underpinnings for DAMP's performance, predicting strong adsorption and stability. The data obtained from the Langmuir adsorption isotherm for corrosion studies also supports a favorable and spontaneous adsorption process.
