“…This indicates the inhibition of the cathode reaction on polarization. It is clear that if the oxygen level is reduced in a 3.5% NaCl solution, the corrosion-oxidation-reduction reaction in seawater (reactive NaCl 3.5%) will be inhibited [27,28]. The inhibitor acts as anodic in this experiment, which is distributed due to metal solubility and absorption of the inhibitor at anodic potentials, while the metal specimen is related to the evolution of hydrogen at the cathodic potential [29].…”

“…As described in Figure 3 for the relationship between concentration and inhibition efficiency, that the addition This shows that with the addition of an inhibitor to the solution, the resulting current density tends to decrease. A decrease in current density implies to decrease the corrosion rate [27]. The analysis has clearly indicated the corrosion mechanism that occurs due to the addition of IRSE containing anti-oxidants.…”

The development of organic or natural inhibitors is essential due to their cost-effectiveness and eco-friendliness. In this study, an organic inhibitor derived from red dragon fruit peel waste is employed. The material of interest is heat-treated API 5L Grade B steel. The research assesses the inhibitor’s efficiency in corrosive environments, namely 3.5‰ NaCl solution and pH 3 HCl solution, with varying inhibitor concentrations (5 ppm, 10 ppm, 15 ppm, 20 ppm). Using Tafel analysis and Electrochemical Impedance Spectroscopy (EIS), it is found that the addition of red dragon fruit peel extract substantially reduces the corrosion rate. The highest efficiency is observed in the 3.5‰ NaCl solution (62.4%) and pH 3 HCl solution (87.73%), accompanied by charge transfer resistances of 2.47 x 106 Ω and 1.79 x 103 Ω, respectively. Immersion tests reveal corrosion products, subsequently examined using X-ray Diffraction (XRD) to identify lepidocrocite phases in the 3.5‰ NaCl solution and magnetite phases in the pH 3 HCl solution. This research supports the development of environmentally friendly and effective natural corrosion inhibitors for protecting steel materials in corrosive conditions.

“…It is noteworthy to highlight that the application of pectin extracted from CM white pith as an innovative raw material for use in adsorbents (Kusrini et al, 2018a;Kusrini et al, 2018b), thin films (Bátori et al, 2017), environmentally friendly agents (Situmeang, 2019), and green corrosion inhibitors (Pradityana et al, 2017) is currently being pursued in our laboratory.…”

Citrus maxima white pith was utilized for the isolation of pectin under acidified condition using L-(+)-tartaric acid, at extraction pH in the range of 1.0 and 2.0. The extraction yield and physicochemical properties (ash content, equivalent weight, methoxy content, anhydrouronic acid, degree of esterification) of the isolated pectin was investigated. The highest yield (70.2%) obtained in this extraction was at pH 1.0, 60°C, 120 minutes. The optimized condition of the isolated pectin in this study was based on the yield and physicochemical properties, where pectin extracted at pH 2.0 and 6080°C for 60120 minutes resulted in a 59.6% yield, with low ash content (2.82%), highest equivalent weight (1098.8) for gelling effect and highest DE (39.2%). The findings are within the range for a good quality pectin. The FTIR spectra of the isolated pectin at different pH mediums, but at constant temperature of 70°C and extraction time of 60 minutes were compared. The presence of methyl esterified carboxyl (1696 cm-1) and carboxylate group confirms the presence of pectin. This isolated pectin as an innovative raw material is potentially applicable for adsorbents, thin films, environmentally-friendly agents and green corrosion inhibitors.

“…Several methods have been developed for the conservation of underwater cannonball heritage, such as cathodic protection (Bethencourt et al, 2018;Angelini, Grassini, and Tusa, 2013;Heldtberg, Macleod, and Richards, 2004), aerated and deaerated using NaOH solutions (Kergourlay et al, 2018), using natural products (Abdel-Karim and El-Shamy, 2022;Verma et al, 2017;Palou, Olivares-Xomelt, and Likhanova, 2014;Cano and Lafuente, 2013;Kesavan, Gopiraman, and Sulochana, 2012). Several natural products and chemicals have been used as green corrosion inhibitors, such as anthill (Myrmecodia Pendans) extract (Pradityana et al, 2017); acid medium (Shetty and Shetty, 2017); malonic acid and succinic acid (Thaha et al, 2019). The final stage after corrosion stops on underwater cannonball heritage is coating.…”

This study aims to conserve the underwater cannonball before storing it in a museum. Removing the protective crust of iron artifacts without the correct and proper method can cause rapid corrosion. To prevent damage, artifacts must be conserved in the right solution. Conservation was conducted in four stages during this research project. The first stage is the identification of weathering, and the second stage is the analysis and characterization of the corroded surface using a microscope, XRD (X-ray diffraction), XRF (X-ray fluorescence), and SEM (scanning electron microscopy). The third stage is the passivation/deactivation process, achieved using sodium hydroxide, soapy water and kaffir lime water. The fourth stage is stabilizing/coating the iron cannonball underwater heritage materials as soon as possible using microcrystalline wax to prevent further corrosion. This stage should solve the conservation problems associated with the object so that the object can last for a long time. Dry and wet-activated corrosion was characterized by applying XRD to the obtained mineral akageneite. The akageneite minerals were actively corroded and contained high concentrations of Cl atoms revealing dry and wet activated corrosion of 66.60% and 64.96%, respectively. After being conserved with several steps and NaOH, soapy water and kaffir lime water, inactive corrosion was observed. Based on the results of the analysis performed with XRF, the cannonball does not contain Cl, and the Fe content is 98.99%. The conservation method used in this research is excellent and appropriate for conserving cultural heritage materials, including underwater iron cannonballs.
