“…The resulting impedance diagrams are not perfect semicircles, and this is attributed to the difference in frequency dispersion [85], due to the dissimilarity of the electrochemical system. This dissimilarity results from adsorption of the inhibitor, impurities, roughness, dislocations, and formation of porous layers [86,87]. When the concentration of all C. siliqua extracts increases from 0.5 to 3 g/l, it is noted that the increase in the size of the capacitive loop is well marked, which can be attributed to the load transfer process, and the impedance value obtained in the case of the control is lower than that obtained in the case of C. siliqua extracts.…”

The effect of C. siliqua pulp corrosion inhibition on carbon steel has been studied by gravimetric testing and electrochemical methods. In this study, two raw extracts were prepared from the pod pulp of C. siliqua: the first is methanolic and the second is aqueous. The UHPLC/DAD analysis indicated gallic acid's presence in the extracts (methanolic and aqueous) of C. siliqua as a major compound. The inhibition results achieved revealed that the aqueous extract with gallic acid had a good anticorrosion activity with an inhibition rate of 91.32% at 3 g/l for a temperature of 323 K. Potentiodynamic polarization was performed in 1 M HCl without and with different concentrations of C. siliqua extracts clearly proves that inhibitor extracts behave as mixed type. Adsorption of this inhibitor for different extracts studied on the surface of the carbon steel obeys Langmuir adsorption with negative values of ΔG • ads , suggesting a stable and spontaneous inhibition process.

“…The CBE was dissolved in 1M HCl and diluted to obtain solutions with the necessary concentrations. [ 17 ] Benabbouha et al use three approaches in this work to investigate the mechanism of inhibition of this alga extract: weight loss, potentiodynamic polarisation, and EIS. The results suggest that C. baccata extract operates as a competent mixed type inhibitor, which is supported by the electrochemical data.…”

Corrosion is significant and continuous issue that causes serious problem on environment, properties, our lives and leads to economic losses. So, prevention of corrosion requires more attention. Metal corrosion inhibitors, both inorganic and synthetic, are used to prevent and slow down corrosion, although these inhibitors are hazardous. Thus, green corrosion inhibitors which both environmentally and economically are likely the solution to this problem. A lot of research has been done to discover good corrosion inhibitors from natural sources. Marine algae is one of the most valuable sources of natural marine products because of its ability to survive in the dynamic environment of the ocean and considered a natural source for corrosion inhibition. In this review, various species of marine algae are discussed as green corrosion inhibitors in terms of secondary metabolites, mechanism of inhibition, and methodologies used to evaluate the corrosion rate of different metals in acidic media.

Introduction: Algae are a significant bioactive compounds source, with variation in biological functions including antioxidant, anti-inflammatory and antiviral. Both microalgae and macroalgae biomass are a rich source of high value nutraceuticals and other bio products of commercial value, making algae worth investigating into. Objectives: To analyze bioactive phytochemicals and their antioxidants properties of extracts from algae from lake Taihu, Microcystis aeruginosa, Spirogyra and Seaweed extracted with ultrasound assisted method in comparison to the traditional extraction method, and a subsequent use of the residue in producing biochar. Materials and Methods: The different algae species viz Microcystis aeruginosa, Spirogyra and Seaweed were subjected to ultrasonic and thermostatted water bath extraction with a 70% ethanol and 30% water (v/v) as solvent. The extracts were characterized using gas chromatography-mass spectrometry. The total phenol and flavonoid and antioxidant activities were assessed in vitro viz hydroxyl radical (•OH) scavenging activity, ferric-reducing antioxidant property, total antioxidant capacity and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) activity. Results: The chemical analysis indicated the existence of bioactive compounds such as alkaloids, phenols, tannins, flavonoids, terpenoids, steroids, proteins, carbohydrates, phytosterols, quinones, saponins, coumarins and glycosides. In vitro screening of the extracts also showed good antioxidant capacity (hydroxyl radical (•OH) scavenging activity, ferricreducing antioxidant property, total antioxidant capacity and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) activity), the extracted compounds are of biological and pharmacological importance.The ultrasound assisted extraction method significantly increased yield with 27.0% in comparison to conventional method with 18.6%. Conclusion: The study showed the different algae species were enriched with phytochemicals and that the ultrasound assisted method was an effective extraction method environmentally benignant. A complete utilization of algae biomass was achieved after biochar was made from the residue.
