Agricultural practices in sectors IV and V based on using fertilizers and pesticides. This study assessed the level of stations contamination by pesticides in sectors IV and V of the Ebrié lagoon. Samples of pesticides in water were collected, in both sectors of Ebrié lagoon, from eleven stations during February 2014 to January 2015. Samples were extracted by liquid/liquid and their analysis was done by high-resolution gas chromatography and mass spectrometer (GC/MS) after purification by adsorption chromatography on florisil column. Fourteen pesticides were detected. Principal component analysis showed that Taboth (sector IV) Mopoyem and Gboubo (sector V) were the most contaminated stations with the highest level of simazine at Taboth, about 772.33 µg/L">

Initial trials started for the simultaneous determination of Betaine and Hentriacontane. Dragendorff reagent was tried for derivatization. Both Betaine and Hentriacontane were proved suitable for quantification using this reagent. Subsequently, the plant extract and extract of the product (Neotea Veliparuthi Powder) were analyzed. In samples i.e., plant extracts, Betaine was below LLOQ (lower limit of quantification) even after proper optimization. Consequently Betaine was opted out of development work. Next, Lupeol, Beta-Sitosterol, and Hentriacontane standards were tried together with Dragendorff reagent. Dragendorff reagent was not suitable for Lupeol and Beta-Sitosterol. Hence, another reagent, i.e., Anisaldehyde Sulfuric Acid (ANS) reagent was evaluated. Lupeol and Beta-Sitosterol were properly derivatized using ANS reagent. Hentriacontane was not derivatized using the same reagent and hence it was decided to opt it out. Based on the literature review, Kaempferol was tried along with Beta-Sitosterol and Lupeol. Since Kaempferol has a chromophore group, derivatization was not required. The method was finalized and validation was performed as per ICH (International council for Harmonisation) guidelines">

Corrosion Inhibition of Mild Steel Using Green Technology

Beena Kumari K.S., Aditya A. J., Ajna Sakeensha, Anjali Sunny, Amrita, M. K. and Anjali Suresh, S.,DOI: 10.24214/IJGHC/GC/13/3 /21724

Pure metals and their alloys are corroded by chemical or electrochemical reactions with the surrounding environment. Different factors like surface impurities, pressure, and temperature, and solution activity make corrosion. To save from this loss, industries have developed various corrosion protection methods. Corrosion inhibitors being among them are widely used in different sectors because of their low cost, strong adaptability, simple process, and economic efficiency. In this project corrosion inhibition of mild steel was carried out   using powders of Hibiscus Leaf (Hibiscus rosa-sinensis), Rosemary Leaf (Rosmarinus officinalis), Marigold flower (Tagetes erecta), Amla (Emblica officinalis) and Aloe vera     gel (Aloe barbadensis miller). Each of these natural substances has properties that can potentially contribute to corrosion inhibition. By conducting weight loss method, the Rosemary extract performed as an effective corrosion inhibitor in 0.1M HCl at ambient temperature and the Aloe vera gel performed as the least corrosion inhibitor in 1M HCl at ambient temperature, from the taken samples. this project serves as a stepping stone towards greener and more responsible corrosion inhibition practices, offering promising prospects for environmentally conscious applications in various sectors.">">

Millets and Health: Review on Nutritive Composition and Protective Well-Being Benefits

Vinay M. Raole and Vaidehi V. Raole,DOI: 10.24214/IJGHC/GC/13/3 /22540

Millets are one of the oldest foods known to humans and are comparable to major cereals with respect to their nutritional features possibly the first cereal grain to be domesticated.  They are a major food source in arid and semi-arid parts of the world especially in Africa and Asia. Since beginning of civilization, millet has been widely used in Asia and India as well as a main food source. Hence, millets come forward as a valuable addition to one's diet.  Millet grain is highly nutritious with good source of energy rich quality protein, rich in minerals, fatty acids, minerals, dietary fibre, phytochemicals, polyphenols and vitamins. Folk medicine also places a considerable emphasis on keeping well-adjusted energy levels and vitality by the use of millets. Typical millet protein contains essential amino acids especially the sulphur containing amino acids. The protein content of foxtail millet, proso millet and pearl millet are comparatively higher than the protein content in wheat. Kodo, little, foxtail and barnyard millet are having higher fibre content.  The millets are the source of antioxidants, such as phenolic acids and flavonoids. Millets tiny grain is gluten free, so least allergenic and most digestible foods. Due to which it is characterized to be a potential prebiotic and can enhance the viability or functionality of probiotics with significant health benefits. The nutritional significance of millets demands for an examination of the nutritional characteristics and functional properties of various millets. Processing millet by milling removes the bran and germ layers that are rich in fibre and phytochemicals, causing significant loss.">">

Catalysts in Green Chemistry: Enhancing Efficiency and Minimizing Environmental Impact

Prashanthi. M,DOI: 10.24214/IJGHC/GC/13/3/24150

Green chemistry is dedicated to designing chemical products and processes that reduce or eliminate harmful substances, thus promoting sustainability and minimizing environmental harm. Catalysts are critical to achieving these goals by enhancing reaction efficiency, selectivity, and energy conservation. This study examines advancements in catalytic technologies that align with green chemistry principles, focusing on their positive impact on environmental sustainability. The study covers various types of catalysts, including homogeneous, heterogeneous, and biocatalysts, each with unique advantages and challenges.

 Homogeneous catalysts, known for their high selectivity, are evaluated for their applications in fine chemicals and pharmaceuticals, particularly recent advancements addressing separation and recycling challenges. The role of heterogeneous catalysts in industrial-scale processes is highlighted, emphasizing their ease of separation and reuse, which is crucial for waste reduction and energy efficiency. Additionally, the study explores biocatalysts, such as enzymes and whole-cell systems, noted for their remarkable selectivity and mild reaction conditions, making them ideal for sustainable operations in the pharmaceutical and food industries. Noteworthy case studies illustrate the effective application of catalytic processes that adhere to green chemistry principles, demonstrating significant reductions in hazardous waste, lower energy requirements, and improved atom efficiency. Innovations in catalyst design, including nano-catalysts and supported catalysts, are discussed to showcase potential improvements in catalytic efficiency and environmental benefits.

 The study also addresses the challenges of scaling up these technologies, considering economic and practical aspects. The integration of catalytic processes with renewable feedstocks and alternative energy sources, such as solar or wind power, is examined to achieve truly sustainable chemical production. In conclusion, catalysts are vital tools in the pursuit of green chemistry, offering substantial improvements in efficiency and environmental impact. Ongoing research and development in this field have the potential to advance sustainable practices, leading to a more environmentally friendly and sustainable future.
