Film Development

In the present work, corrosion inhibition of low carbon steel in a 1M H2SO4 solution by pectin nanoparticles extract was studied by potentiostatic and weight loss methods. Increasing the acid concentration leads to an increase in the corrosion rate of the electrode. The variable conditions of the pectin nanoparticles used in this investigation are (2 to 10g/l at 25oC). It was found that the concentrates acts as a compelling consumption inhibitor for gentle steel in an acidic medium. The hindrance process is credited to the adsorbed film development of the inhibitor on the metal surface of that protects the metal against corrosion. It was observed that the efficiency of the inhibition rose with increased inhibitor concentration up to the maximum level of 92% for 10 g/l at 25 oC. The results showed that the corrosion rate without the inhibitor was 2.263mpy while with the inhibitor 0.179 mpy, meaning that the rate of corrosion improved more than 90%. The results of the immersion time (1 h) at 25oC on the inhibition of the corrosion also indicated improved corrosion resistance. The results demonstrated that an extract of pectin nanoparticles could serve as an excellent eco-friendly, green corrosion inhibitor. Fourier- transform infrared spectroscopy (FTIR) results indicate that these nanoparticles contain various chemical bonds (C-C, CH2, C-O-C, and cellulose) with metal surfaces, lead to producing a barrier layer that protects the surface.

The Relationship

The investigation of the antimicrobial and antioxidant activities of palm kernel oils extracted from varieties Dura (oil D) and Tenera (oil T) of oil palm (Elaeis guineensis Jacq.) and the relationship to their chemical composition were carried out in this study. The results obtained show that oil D had the greatest antimicrobial activity. The analysis of gas chromatographic coupled to mass spectrometry (GC-MS) showed that this oil D contained in addition to the lauric acid, the undecylenic acid which both possess antimicrobial activity. This undecylenic acid was not identified in oil T. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the Fe3+ reduction test (FRAP) used to evaluate the antioxidant activity of the palm kernel oils had showed that oil T had the greatest antioxidant activity with a concentration inhibiting 50% of the reaction (IC50%) of 750 mg/L. It was also noted that, this oil T had also the highest contents in polyphenols, α-tocopherol and sterols with predominance of β-sitosterol. Moreover, the β-sitosterol is known to possess a regulatory role of the immune system.The findings of this study provide thus, useful information which may help customers to make the best choice in the consumption of these oils.

Abstract The use of inhibitors is one of the most practical means for protecting metals against corrosion, especially in acidic media. The interest is to use organic compounds as inhibitors due mainly to their inherent and non-toxic nature. Amino acids are attractive as corrosion inhibitors because they are nontoxic, relatively easy to produce with high purity at low cost, and are soluble in aqueous media. Lysine, one kind of amino acid is used as inhibitor. The aims of this study are to show corrosion protection efficiency of lysine and to explain the mechanism of corrosion. The experimental results demonstrated that the lysine offered protection for low alloy carbon steel in aggressive environments like H2SO4. Materials under investigation are two types of low alloy carbon steel marked as: Steel 39, Steel 44 (usually applied to concrete as reinforcing bars). The corrosion media consists in sulfuric acid in presence of chloride ions, in form of NaCl (H2SO4 1M + Cl- 10-3M). Potentiodynamic polarization methods are used for inhibitor efficiency testing. Potentiodymanic polarization measurements showed that the presence of lysine in acidic solution decreases the corrosion current to a good extent. The corrosion inhibition efficiency improves with the increase of the lysine concentration. The use of this inhibitor (1g/L) protects steel 39 in acidic media with 78.88% efficiency. That means lysine is a good corrosion inhibitor for these aggressive conditions.

Background: African oil palm (Elaeis guineensis Jacq.), a perennial crop that originated from Tropical rainforest of West Africa, is one of the most important economic oil crops in Nigeria providing income for rural and semi-urban folks. This study described the ethnobotany of the plant and evaluated the extent to which it contributes to the livelihood strategies of the Ikale and Ilaje speaking people of Ondo State, Nigeria. Methods: Interviews were conducted in the local language and questionnaires were administered to willing respondents. Photographs of tools/machines used in the production of palm oil and allied products were taken. Drawings of the tools were generated on site. Results: The plant is the principal source of palm oil. Major processing tools of palm oil include cracker, presser, digester, and boiling trough. Other products that are derived from oil palm parts are palm kernel oil, kernel meat (for livestock feed), kernel shells (for fuel), palm wine, broom, fish trap, and traditional soap. All these products are made using indigenous methods. They feature in medicinal preparations, traditional ceremonies and are important household commodities. Conclusions: The products derived from oil palm tree serve as means of livelihood in the study communities and are local resources used in everyday activities of the people. The indigenous production methods observed further emphasize the role these products play in the economy of oil palm product makers and sellers. Sustainable tapping of palm wine should be encouraged in order to derive maximum benefits from oil palm tree. Keywords: Ethnobotany, Economic Botany, African Oil Palm, Ondo State, Nigeria
