The thermal and photostability nature of these coloured contaminants which makes them difficult to be eliminated from our water system is of great concern. Researchers are continually putting massive attention on the possibilities of improving existing methods and technologies, developing novel strategies, and bring about solutions to subdue these dye-related water contamination problems which will be economically and environmentally friendly. One of the most sustainable technology or method employed in the decontamination and purification of coloured wastewater is adsorption. It possesses several advantages as it has simple and easy design of operation and is highly economical. Metal-organic frameworks (MOFs) play substantial roles under this application as a new class of porous adsorbents that are characterized by a highly crystalline molecular structure and relatively large surface area which is a significant parameter to be considered in adsorption processes. They are also recommended as a good choice of sorbents employed in wastewater purification technologies as a result of their tunable features. This research study aimed at providing a comprehensive review of recent studies on the adsorptive use of MOFs for the removal of these developing organic pollutants from wastewater.https://www.jchemrev.com/article_141481_b1af11c230a89fb622ebcf48a2023893.pdfSami Publishing CompanyJournal of Chemical Reviews2676-68684120220101Recent Advances in Isolation and Antimicrobial Efficacy of Selected Strychnos Species: A Mini Review152414193410.22034/jcr.2022.314381.1129ENJibrin UttuAhmedDepartment of Chemistry, Federal University Gashua, Yobe State, Nigeria0000-0002-4089-5529Muhammad SaniSallauDepartment of Chemistry, Ahmadu Bello University, Zaria, Nigeria0000-0002-0299-2467Ogunkemi Risikat AgbekeIyunDepartment of Chemistry, Ahmadu Bello University, Zaria, Nigeria0000-0002-0272-3128Hamisu IbrahimDepartment of Chemistry, Ahmadu Bello University, Zaria, Nigeria0000-0003-3022-7671Journal Article20211110Treatments of various diseases in pharmacology through herbs have begun a long time ago. Herbal medicines have been in practice since time immemorial, and over 80% of the global population depends on medicinal plants to treat disease. Medicinal plants contain active ingredients for functional therapeutics purposes, such as antimicrobial agents. Examples of those medicinal plants are found in different plant species belonging to different families such as <em>Boraginaceae</em>, <em>Loranthaceae</em>, <em>Urticaceae</em>, <em>Plantaginaceae</em>, <em>Loganiaceae</em>, <em>Lamiaceae, </em>among others. The genus, <em>Strychnos</em> belongs to the family of <em>Loganiaceae</em> and consists of about 200 species. Isolated compounds and antimicrobial of a few species from the <em>Strychnos </em>genus have been reported recently. This review aimed to detail the isolated compounds and antimicrobial efficacy of selected <em>Strychnos</em> species reported within 2014 – 2021. Based on the MIC result, the antimicrobial efficacy indicated that extracts of <em>S</em>.<em> madagacariensis</em> and <em>S</em>.<em> pungens</em> have the highest activity against <em>S</em>.<em> typhi</em>, extract of <em>S</em>.<em> lucida </em>have highest activity against <em>B</em>.<em> cereus</em> and <em>S</em>.<em> pyogenes</em>, extract of <em>S</em>. <em>spinosa</em> showed better activity against <em>K</em>.<em> pneumonia</em> and <em>B</em>.<em> subtilis</em>, extract of <em>S</em>.<em> nux-vomica</em> has highest activity against <em>S</em>.<em> aureus</em>,<em> P. aeruginosa</em> and <em>E</em>.<em> faecalis</em> while extract <em>of S</em>.<em> colubrine</em> exhibited excellent activity against <em>C</em>.<em> perfringens</em>. About thirty compounds belonging to alkaloids, terpenoid, terpene, steroids and other class and their pharmacological properties were reviewed in this study. This is concluded that the <em>Strychnos </em>species under this review contains a wide variety of compounds belonging to different classes of phytochemical, possessing significant antimicrobial activity.https://www.jchemrev.com/article_141934_f51241d94b0ca14527b64bc8c6e4a2bf.pdfSami Publishing CompanyJournal of Chemical Reviews2676-68684120220101An Outline to Preparation of Biological Active Benzimidazoles Using Microwave Approach253914443410.22034/jcr.2022.316076.1132ENPearl RheaFernandesDepartment of Food Nutrition and Diet, Milagres College, Hamapankatta Mangalore, IndiaPrachi PatilDepartment of Chemistry, Karmaveer Bhaurao Patil College, vashi, IndiaRupali CSheteDepartment of Chemistry, CKT College Panvel, India0000-0003-1694-2709Journal Article20211120Benzimidazole and its derivatives have a lot of diverse biological activities, including antimicrobial, antiviral, antidiabetic, anticancer activity.

This review critically examines heavy metal and organic pollutants' role in wood treatment sites and their etiological consequences. These pollutants are not only recalcitrant but also tenacious to degradation under ordinary conditions. Although some heavy metals are essential to human health, they are toxic at elevated concentrations. Heavy metals feature carcinogenic properties and cause serious health risks to live systems and the environment because of their bio-accumulative, non-degenerative, and refractory characteristics. On the other hand, organic pollutants are readily introduced into the ecosystem from irresponsible use of detergents, volatile organic compounds, paints, pesticides, and wood preservatives. During the wood treatment process, various chemicals are used to enhance durability. Nevertheless, the use of wood preservatives such as chromated copper arsenate (CCA) and pentachlorophenol (PCP) potentially induces pollutants considered detrimental to human health and the ecological environment. Remediation of wood treatment sites using phytomanagement strategies and nanotechnologies has been presented in this review. Therefore, some challenges and recommendations for further research and applications are herein presented.https://www.jchemrev.com/article_144486_462fcc69e7f1b87e9cc36707c499623c.pdfSami Publishing CompanyJournal of Chemical Reviews2676-68684120220101Scale Corrosion of Metallic Materials in Water Systems-A Review678014536010.22034/jcr.2022.326770.1141ENIhssin AbubakerAbdalsamedDepartment of Chemistry, Faculty of Sciences, Sebha University, Sebha Libya0000-0002-5573-8374Ibrahim AliAmarDepartment of Chemistry, Faculty of Sciences, Sebha University, Sebha Libya0000-0003-2354-0272Abubaker AhmedSharifLibyan Advanced Centre for Chemical Analysis, Libyan Authority of Science Research, Tripoli, Libya0000-0003-3626-7690Masood AbdulsalamGhnimDepartment of Geology and Environment, Faculty of Sciences, Bani waleed University, Libya0000000168268060Abdusatar AbduallahFaroujDepartment of Corrosion, Total Oil Company, TripoliJamal AliKawanDepartment of Production, Akakus Oil Company, TripoliJournal Article20220127Scale corrosion is the worst type of corrosion compared to other types of corrosion due to the tendency to attack pipes is higher even when the pipes are made of non-metals such as polymers.
