Impact of some pyrrolidinium ionic liquids on copper dissolution behavior in acidic environment: experimental, morphological and theoretical insights

Abstract

The inhibitive and adsorption activity of some pyrrolidinium ionic liquids (ILs) for the dissolution of copper in 1 M HNO3 solution was tested using chemical methods such as weight loss and electrochemical techniques.

Performance and Mechanism of Alkylimidazolium Ionic Liquids as Corrosion Inhibitors for Copper in Sulfuric Acid Solution

“…Copper and its alloys are widely utilized as an important material in various industrial applications such as microelectronic, military, and civilian living life owing to its electrical conductivity, good thermal properties, mechanical workability, good availability, cheap, and corrosion resistance properties. However, copper will be corroded unavoidably in acid surroundings and humid environments, greatly limiting its use [1][2][3][4][5][6][7][8][9][10][11][12][13]. The common ways for corrosion prevention are isolation protection, electrochemical protection, and adding inhibitors.…”

“…The common ways for corrosion prevention are isolation protection, electrochemical protection, and adding inhibitors. One effective and useful approach to protect copper metals against the corrosion problem of acid solutions is adding corrosion inhibitors, which are often ionic liquids because they have many special properties such as better thermal stability, good solubility, high conductivity, wider electrochemical window, and so on [5,7,12,13]. Ionic liquids (ILs) are currently used as fascinating compounds which are salts with liquid formation at room temperature or low temperature (<100°C) in intense examination [14].…”

Recent developments in sustainable corrosion inhibitors: design, performance and industrial scale applications

“…Therefore, a proper combination of hydrophilicity and hydrophobicity is highly essential while designing the effective corrosion inhibitors [389,402]. The anticorrosive effect of pyridinium [378,[403][404][405], pyrrolidinium [406][407][408], ammonium [9,[409][410][411][412] and phosphonium [409,413] based ionic liquids are also reported in the literature. 91.29% at 100 ppm [401] Because of their high solubility and environmental benign nature ionic liquids are also tested as anticorrosive agents for other metals and alloys.…”

Molecular dynamics simulations of Y(iii) coordination and hydration properties

“…Based on the chemical composition of the Y(III) complex ions obtained in the MD simulations, geometric optimization of the Y(III) complex ion structure and calculation of the characteristic UV absorption spectrum were performed by DFT. 32 The DMol3 module in Materials Studio 8.0 was used for DFT computation. 33 The GGA/ PBE method was selected, 34 and the base was set to DND 4.4.…”
