“…Data pada Gambar 4 tersebut menunjukkan bahwa seiring dengan semakin lama perendaman sampel kupon baja di dalam medium, terjadi peningkatan laju korosi. Peningkatan waktu perendaman berarti memperlama waktu kontak antara zat korosif (medium, limbah minyak bumi) dengan sampel kupon baja, sehingga meningkatkan kelarutan ion besi di dalam medium korosifnya [17].…”

Korosi merupakan permasalahan umum yang terjadi pada peralatan proses dari bahan logam, khususnya pipa baja karbon, di industri pengolahan minyak bumi. Korosi tersebut dapat terjadi dengan laju bervariasi tergantung pada berbagai faktor, seperti jenis medium, suhu, dan waktu kontak antara bahan logam dengan medium. Laju korosi dapat hambat dengan teknik penambahan inhibitor ke dalam medium. Tujuan penelitian ini adalah mempelajari pengaruh suhu dan waktu perendaman pipa baja API 5L Grade B di dalam limbah minyak bumi dengan penambahan inhibitor sikloheksilamina terhadap laju korosinya. Sampel pipa baja API 5L Grade B disiapkan dalam bentuk kupon, potongan pipa dengan ukuran tertentu. Suhu perendaman dipelajari pada 30, 45, 60, 75, dan 90 C, sedangkan waktu perendaman dipelajari selama 48, 72, dan 96 jam. Hasil penelitian menunjukkan, perendaman pada suhu 90 C dengan penambahan inhibotor memberikan laju korosi terbesar, yaitu 0,788 mm/tahun posisi BLC (bottom line corrosion) dan 0,115 mm/tahun pada posisi TLC (top line corrosion). Sedangkan perendaman selama 96 jam dengan penambahan inhibotor memberikan laju korosi terbesar, yaitu 0,807 mm/tahun posisi BLC dan 0,133 mm/tahun pada posisi TLC.

“…HNO3 > H2SO4 > HCl. It has been obtained that increase in the concentration leads to increase in rate of corrosion [11]and the properties of suphuric acid are given inFigure 6. It is attributed due to the shedding of nitrite, sulphate and chloride ions on the surface of the metals resulted in the detrimental formation of magnetite compounds and hematite compound.…”

The growth in the industrial technology and communication sectors has enhanced the usage of electronic gadgets exponentially. Thus, it becomes highly essential to find new solution to utilize or dispose these e-wastes, in order to reduce the e-waste generation. Various reports mentioned that the major component of these e-wastes is their Printed Circuit Boards. Therefore, a new ideology is proposed to use these boards to produce a new coating with good corrosion resistance. At first the boards were separated from the discarded electronic appliances and various electrical elements were separated from these boards. Then the plain circuit boards are pulverized into fine particles and mixed with paint in 3 different proportions ranging from 1:4 to 1:2. The resulting mix was applied over the steel specimen and tested for corrosion resistance. The assessment was done in the aspects of contact angle, weight loss percentage, potentio dynamic polarization technique and electro chemical impedance spectroscopy. From the results it was clear that increase in the addition of printed circuit powder content in the corrosion proof paint coating enhanced the efficiency of the corrosion resistant behaviour 3.5 times than the specimen with uncoated steel specimens. This development of corrosion resistant behaviour of printed circuit powder was attributed from the inertness offered by the presence of silicon dioxides towards the corrosive fluids. Although, the coating of 1:2 proved to be optimum to protect the steel elements from the aggressive corrosion environment, by considering the workability aspects the 1:3 combination was suggested for the innovative development of anti-corrosion paint coating from the e-waste resources. HIGHLIGHTS Life cycles of every electronic wastes end with the hazardous challenging disposals Innovative utilizations of these electronic wastes for the corrosion resistant structural applications were detailed An anti corrosive coating for steel reinforcement was developed from the waste printed circuit boards Coating by printed circuit board powder enhanced 3.5 times more protection from the corrosion GRAPHICAL ABSTRACT

Carbon steel is very important because it is widely used in many industrial and engineering fields, such as oil and gas. However, engineering materials accounted for 85% of yearly steel production due to their accessibility and affordability. As a result of strict environmental rules and a growing ecological consciousness among scientists, "green" ways to minimize corrosion have been created. In the current study, burghul extract is demonstrated to be an effective corrosion inhibitor and was utilized as an environmentally acceptable anti-corrosive material for carbon steel in a 1M HCl solution. The effectiveness of mitigation methods such as mass loss, electrochemical impedance spectroscopy, frequency modulation, and potentiodynamic polarization (PP) was calculated. Meanwhile, dispersion X-ray (EDX) and scanning electron microscopy (SEM) methods were used to analyze surfaces. Results obtained showed that temperature and extract concentration both affect how effective the mitigation is. The inhibition is attributed to the development of a protective layer that slows the dissolution of carbon steel at its surface. The Langmuir model was validated by the adsorption of burghul extract on steel. The adsorption of the extract affected both anodic and cathodic reactions. Tafel curves showed that burghul is a mixed inhibitor. The Nyquist curves confirmed that the burghul extract prevents the disintegration of steel in acidic media without changing the dissolution reaction mechanism. By using ATR-FTIR analysis and SEM inspection, the burghul extract's adsorption on the metal carbon steel was verified. A maximum inhibitory efficacy of 95% was reached at 313 K using 300 ppm of the Burghul extract, which is thought to be a promising result.
