NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of developing innovative solutions for material protection. Our latest research highlights the exceptional capabilities of organophosphorus derivatives, specifically a compound known as DAMP, in the critical field of copper corrosion inhibition. Copper, a vital metal in numerous industries, is particularly susceptible to degradation when exposed to acidic conditions. Understanding the copper corrosion inhibitor in acid mechanisms is crucial for developing effective protective strategies.

This cutting-edge study delves into the science behind DAMP's remarkable performance. Through a comprehensive analysis employing techniques such as SEM EDX analysis of corrosion inhibitor and FTIR analysis of organophosphorus inhibitor, we have elucidated the fundamental principles governing its effectiveness. The effect of inhibitor concentration on corrosion rate was a key focus, revealing that DAMP provides significant protection even at low concentrations, with optimal results observed at 180 ppm. This concentration yielded up to 96.2% inhibition efficiency for copper in hydrochloric acid and 92.6% in sulfuric acid.

The core of DAMP's protective action lies in its robust adsorption onto the copper surface. The adsorption mechanism of copper corrosion inhibitor showcases how DAMP molecules, rich in heteroatoms like nitrogen, oxygen, and phosphorus, strongly bind to the metal. This binding is further enhanced by the molecule's electronic structure, as confirmed by quantum chemical study of corrosion inhibitors. The formation of a stable protective film on the copper surface acts as a formidable barrier, preventing direct contact with corrosive agents and significantly reducing the rate of degradation.

Further validation comes from the adherence to the Langmuir adsorption isotherm for copper, indicating a well-ordered and efficient adsorption process. The research not only confirms DAMP's superior anti-corrosion properties but also underscores its potential as an eco-friendly and cost-effective solution for industries facing the challenge of copper corrosion in acidic environments.
