The influence of certain thiadiazole derivatives on the corrosion of Muntz metal (60Cu–40Zn) in sulfide-polluted artificial seawater was analyzed using electrochemical and physiochemical studies methods. The surface morphology was examined by SEM to determine this inhibition mechanism. Elemental composition of the corroded alloy specimens was investigated in the presence and absence of thiadiazole derivatives using energy-dispersive X-ray analysis (EDX). Thiadiazole derivatives were found to successfully suppress Muntz metal corrosion. Adopting the weight loss method, the optimum concentration of inhibiting thiadiazole derivatives was 2.32 mM owing to the thiadiazole surface coverage and adsorption with increasing concentration. Among the derivatives investigated, N-(5-(4-aminophenyl)-1,3,4-thiadiazole-2-yl)-2-diphenylamino) acetamide (ATPA) showed the highest corrosion protection efficiency. EIS studies showed that charge transfer resistance occurs because of the presence of an inhibitor. Moreover, increasing thiadiazole concentration decreased the double-layer capacitance (Cdl) value because less charged species were attracted to the metal surface. Potentiostatic current–time transient techniques showed that ATPA hindered the corrosion rate owing to the substituted thiadiazoles. Polarization measurements clearly showed that the inhibitors suppressed both anodic and cathodic reactions. Consequently, accelerated leaching studies showed concentrations of Zn and Cu released from the alloy reducing as concentrations of inhibitors increased, in addition to the corrosion protection efficiency (%) increasing. The highest value was obtained at 2.32 mM of inhibitor. In conclusion, this study demonstrates that these compounds inhibit corrosion via chemisorption of organic compounds. Among these compounds, ATPA was found to offer better corrosion inhibition than others.

Environmental pollution by microplastics (MPTs) generated by physical destruction of plastics is a global problem with enduring and biohazardous threats. In recent decades, the expulsion of MPTs from the environment has affected human health and the green atmosphere. Currently, several significant high-tech innovations have been designed and reported to clean dangerous MPTs. Among them, nanotechnology-based biomaterials have received potential attention for bioremediation. This chapter focuses on collective microbial power technologies (MPTs) present in the natural green environment and explores techniques utilizing bionanomaterials for their effective cleaning. It is also providing information on bioremediation and designing modern green-environment approaches to control and purge MPTs in a short time. Moreover, we describe the different techniques with their advantages and disadvantages, which are also discussed. Finally, we conclude with the future outlook for delivering the path to a complete purge of MPTs. © 2024 American Chemical Society.
