Unfortunately, <em>mango</em> leaves are generally dumped as agricultural waste due to their abundance, resulting in significant waste and environmental pollution. In this study, electrochemical and weight loss techniques were utilized to investigate the inhibitory mechanism of <em>mango</em> leaves extract (MLE) on the corrosion of X70 steel in 1 M HCl. The results indicated that MLE was an excellent corrosion inhibitor for X70 steel to resist corrosion in an acidic environment, and the inhibition efficiency was effectively improved by increasing the inhibitor concentration and decreasing the temperature. Electrochemical tests have shown that MLE functions as a corrosion inhibitor with a mixed-type mechanism. Fitting the adsorption isotherm with electrochemical data, confirmed that MLE demonstrates corrosion resistance on metal surfaces through adsorption, and this adsorption conforms to the Langmuir isotherm. The adsorption phenomenon was deeply investigated by using atomic force microscopy (AFM) and scanning electron microscopy (SEM). MLE is further proven to interact with the steel surface to generate an adsorption layer that prevents steel corrosion in an acidic environment. In particular, the density-functional tight-binding (DFTB) calculations results also suggest that the π electron and lone-pair electrons in the main components of MLE are conducive to enhancing the adsorption of corrosion inhibitor molecules on the iron surface, to achieve a more effective inhibition effect. Furthermore, the toxicity prediction indicates that the MLE components are nearly non-toxic, which complies with environmental protection regulations. MLE has excellent corrosion resistance, with a corrosion inhibition efficiency of nearly 90 % at a concentration of 400 mg/L, while also helping to solve agricultural waste management challenges.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":null,"pages":null},"PeriodicalIF":8.6,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, chitosan-based hybrid hydrogel beads were fabricated by incorporating naturally available siliceous micro- and nanoparticles, namely diatomite and bentonite, with different mass ratios. Morphology, swelling behavior, mechanical stability, and ultimately, Methylene Blue (MB)-adsorption performance of the hydrogel beads were comprehensively evaluated in terms of filler dispersion and interactions between the fillers and the matrix. Results revealed that while the simultaneous incorporation of inorganic additives inside the chitosan backbone reduced the swelling degree, the mechanical stability was significantly ameliorated when the 1:1 diatomite-bentonite mass ratio was exploited inside the chitosan matrix. That can be attributed to the well-dispersed fillers and enhanced mechanical entanglements, as well as the strengthened physical interactions between diatomite-bentonite and chitosan matrix. When the hybrid filling system was applied, MB removal efficiency increased synergistically by over 246 % compared to bentonite alone and 268 % compared to diatomite alone, even at low MB concentration (10 ppm). The MB adsorption kinetics and isotherm were also studied. The adsorption kinetics of MB were well-fitted for all compositions using the pseudo-second-order model. The isotherm data for optimum beads indicate that the Freundlich isotherm model provided the best fit, suggesting the multilayer adsorption with a non-uniform distribution of adsorption heat.
