“…Utilization of natural water for both domestic and industrial purposes is related with scale and corrosion problems. Water containing dissolved gases such as O 2 and CO 2 can cause corrosion of metal equipment [1,2], and the presence of Ca 2+ and Mg 2+ cations leads to scaling [3,4], especially when water is used in heat exchange processes. As a result of corrosion, water quality deteriorates and metal equipment requires repairs and replacement more often.…”

The Raphanus sativus L. ethanol extract was prepared by radish cake maceration in ethanol end tested as a scale and corrosion inhibitor of mild steel in tap water. Antiscalant efficiency was tested with electrochemical and thermal scaling techniques, and changes in hardness content were determined titrimetrically. No deposits were found on the metal surface at the extract concentration of 10 mL/L in chronoamperometry test, and scaling suppression was established 5 times in thermal scaling conditions. The linear polarization resistance technique was used to determine corrosion rate. Inhibition efficiency was found to be 75% in thermal scaling conditions. The formation of the surface film was responsible for both scaling and corrosion suppression on mild steel surface as was established with FT-IR spectroscopy and SEM. The surface film was found to contain polymerization products of isothiocyanates.

“…Despite the significant development of industrial synthetic substances production, metals remain the main structural material that is indispensable in a series of industries. Given the increase in the volume of metal production, there is an enhanced need to protect them against corrosion [1]. It is worth noting that most domestic oil pipelines are operated under conditions of intensive internal corrosion; the operation of wells is associated with the release of mineral particles, in particular sand, which also leads to the wear of the equipment.…”

Для боротьби з корозією використовують корозійностійкі сплави, що вимагає великих затрат і не є достатньо надійним засобом, та інгібітори корозії, які потрібно постійно вдосконалювати для підвищення їх ефектив ності та зменшення собівартості. Оскільки корозія характеризується руйнуванням мате ріалу внаслідок взаємодії із навколишнім сере довищем, то одним із доцільних методів її мінімізації є використання інгібіторів. Тому актуальним завданням охорони навколишньо го середовища та економічного розвитку країни є розробка ефективних засобів захисту металів від корозії. Отриманий інгібітор АС2 (розчин суміші 2алкілімідазолінів в метанолі) досить ефективно захищає сталь від корозії у водно нафтових сумішах при високих концентра ціях мінеральних солей у воді. Ефективність інгібітору практично не залежить від спів відношення об'ємів нафти та концентрованих водних розчинів хлориду натрію. При викорис танні інгібітору при концентрації 50 мг/дм 3 ступінь захисту сталі від корозії перевищував 90 %. Пов'язано це з тим, що захист сталі від корозії відбувається за рахунок сорбції імідазо лінових складових на поверхні металу та сорб ції органічних складових нафти на гідрофобних алкільних групах 2алкілімідазолінів. При цьому гідрофобізація поверхні металу відбувається в присутності незначних кількостей нафти. Показано, що у суміші, що містила 200 см 3 3 % розчину хлориду натрію та 800 см 3 нафти, при концентрації оцтової кислоти відповід но 0,5 та 3,0 г/дм 3 , при температурі 80 °С при дозі інгібітору 15-50 мг/дм 3 , ефективність була 72-92 %. Це дозволяє вирішити проблему раціонального природокористування та забез печує перехід до використання екологічно без печних енергоефективних технологій Ключові слова: інгібітор корозії, 2алкілімі дазолін,воднонафтова суміш, швидкість коро зії сталі, ступінь захисту від корозії

“…For mild steel protection in chloride-containing media, a large number of inorganic and organic corrosion inhibitors have been studied. The use of traditional corrosion inhibitors is now limited because of an increasing concept of "green chemistry" in the field of science, technology, and engineering [1][2][3][4][5][6]. This has prompted researchers to find out some cheap and effective "green" inhibitors [1,[7][8][9][10][11].…”

The present study was carried out to identify the components present in the ethanol apricot pomace extract by GC-MS analysis. Various experimental models including iron(III) reducing capacity, total antioxidant capacity, DPPH radical scavenging activity were used for characterization of antioxidant activity of the extract. Weight loss investigation, potentiodynamic polarization, and FTIR techniques were used to study the corrosion inhibition. The maximum inhibition efficiency of 94.6% was achieved by using 500 ppm of the inhibitor. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) analysis were used to characterize the protective film. AFM also illustrated an improvement in the surface properties of the samples in the presence of APE. The influence of the immersion period on inhibition efficiency was evaluated. The GC-MS experimental results show that the major compounds of the APE are 3,4,5trihydroxybenzoic acid, chlorogenic acid, 3-(3,4-dihydroxyphenyl)-2-propenoic acid, 2-(3,4-dihydroxyphenyl)-3,5,7-trihydroxy-4H-chromen-4-one, and catechin. The results revealed that in the attendance of the APE and with the immersion time progress up to 48 h, the inhibition capacity of inhibitor was promoted.The mechanism of action of the inhibitor is also discussed. Quantum chemical parameters calculated for the molecules contained in the aqueous extract are interpreted to predict the corrosion inhibition efficiency of the considered extract. The theoretical study gave insights to the active sites, chemical reactivity and possible interaction mechanism between the inhibitor compounds and mild steel surface. The apricot pomace extract studied in this work are potential multifunctional inhibition materials as they showed good antioxidant and anticorrosion properties.
