| Abstract | Quinoline and their derivatives extracted from biodiesel are often used for designing of many synthetic compounds with diverse pharmacological and medicinal proprieties. These kinds of compounds have a wide variety of applications in many fields. They serve as intermediates in certain enzymatic reactions and their use as environmentally safe corrosion inhibitors reveal their importance. The aim of this work is to investigate the corrosion inhibition of cooling circuits in desalinated water by new environment-friendly Quinoline Schiff base. This examination has been determined by potentiodynamic polarization and electrochemical impedance spectroscopy measurements. Results obtained of these methods consistently identify this compound as efficient inhibitor. Those corrosion parameters were determined from current-potential curves; it was found that corrosion rates decrease and percentage inhibition efficiency, surface coverage degree and polarization resistance increase with increasing additive concentration. Impedance measurements confirm these results where it was observed, that the effect of inhibitor addition appears by an increase in the charge transfer resistance and by a decrease in the capacity of interface. The results obtained from the Potentiodynamic polarization measurements are in good agreement with those obtained from the electrochemical method. Quantum chemical parameters are calculated using the Density Functional Theory method (DFT). Correlation between theoretical and experimental results is discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
