The corrosion refers to the process by which metals undergo surface degradation due to an electrochemical reaction with the surrounding intrusive environment, leading to its initiation and acceleration. Corrosion inhibitors are widely recognized as the most effective and cost-efficient method for preventing corrosion. The utilization of conventional and harmful corrosion inhibitors has led to environmental concerns, prompting the creation of eco-friendly, readily available, biodegradable, and economically efficient green substitutes. This review examines the utilization of green corrosion inhibitors sourced exclusively from renewable origins, focusing specifically on recent progress in employing extracts from fruits, vegetables, and rice peels as green corrosion inhibitors. Fruits and vegetables, specifically, contain abundant phytochemicals with corrosion-inhibiting properties. The experimental methodologies employed in corrosion inhibition, along with the underlying mechanism of corrosion inhibition, are extensively examined to elucidate the actual capabilities of these extracts in safeguarding steel in acidic surroundings. The study emphasizes the capacity of fruit and vegetable extracts to serve as environmentally friendly and economical substances that can prevent corrosion, thus contributing to the advancement of green chemistry. This review focuses on the most important inhibitors removed from the peels of fruits, vegetables, and rice, where an efficiency of 98.8% was achieved.</p>","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"3 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141198077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, a group of organic and inorganic acids and surfactants are used in well stimulation processes. In order to reduce the violent attack of the acid solution on the N80 mild steel casing materials and pipes, during the pickling process inhibitors are added to the acid medium, and to avoid the complexity of the inhibition process in the oil and gas fields, which requires organic inhibitors within the green chemistry depending on the nature of the work field such as pipelines and equipment, recovery wells, refineries, etc. Organic acids and acidic gases such as carbon dioxide and hydrogen sulfide complicate the well inhibition problem. Corrosion problems in the oil industry must be dealt with by considering various factors. Acids used in stimulation, the nature and type of reservoir rocks, and oil well equipment, whose operating conditions include casings and tubes, and these form part of the factors affecting corrosion. Thus, it needs to study each case as it is before determining the final opinion regarding the alternative materials. No suitable material can be found to survive the attack of corrosion. The designers and operators of the oil industry must take into account many serious economic and technical problems, the most important and most dangerous of which is the phenomenon of corrosion that is characteristic of the oil industry that deals with highly volatile and sometimes toxic materials and transported by pipelines over long distances and stored in huge warehouses in addition to because it requires a complex operational process that requires high heat and pressure, so if this equipment is so worn out that it is unable to withstand these harsh conditions, then there is no doubt that explosions may occur, which may be accompanied by fires, and sometimes their effect reaches the neighboring equipment and sometimes the entire production unit.</p>","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"90 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigation examined the contact duration, pH, temperature, agitation speed, starting dye concentration, and quantity of nanomaterial on adsorption effectiveness. Experimental results demonstrated a remarkable removal efficiency of 96% for malachite green dye at an initial concentration of 100 ppm in the contaminated solution. Interestingly, the percentage removal exhibited an inverse relationship with dye concentration and temperature, while being directly proportional to other factors.
