    A Green Approach to Landfill Remediation: The Efficacy of Indigenous Zygophyllum coccineum L. and Leptadenia pyrotechnica L. in Phytoremediating a Heavy Oil Flay Ash-contaminated L... by Samir G.M. Al-Solaimani, Abdulrahman Alkurashi, Refaat A. Abohassan, Omer H.M. Ibrahim, Magdi A.A. Mousa

    Published 2025-01-01
    “…The sequence of heavy metal concentrations from highest to lowest in the roots and shoots was as follows: sulfur > aluminum > iron > zinc > manganese > nickel > chromium > vanadium > copper > cobalt. The plants exhibited elevated chromium levels that surpassed the European Union (2002) requirements; however, they remained below Indian regulations. …”

    The contrasting origins of glauconite in the shallow marine environment highlight this mineral as a marker of paleoenvironmental conditions by Tribovillard, Nicolas, Bout-Roumazeilles, Viviane, Abraham, Romain, Ventalon, Sandra, Delattre, Marion, Baudin, François

    Published 2022-12-01
    “…The weakly reducing conditions necessary for the formation of glauconite here are attested by the contents of metallic trace elements sensitive to redox conditions (vanadium, germanium, arsenic, in this case). Our work thus adds a new element to the understanding of the mechanisms of formation of glauconite in shallow environments.…”

    Influence of Irradiance, Flow Rate, Reactor Geometry, and Photopromoter Concentration in Mineralization Kinetics of Methane in Air and in Aqueous Solutions by Photocatalytic Membra... by Ignazio Renato Bellobono, Mauro Rossi, Andrea Testino, Franca Morazzoni, Riccardo Bianchi, Giulia de Martini, Paola Maria Tozzi, Rodica Stanescu, Cristina Costache, Liliana Bobirica, Mauro Luigi Bonardi, Flavia Groppi

    Published 2008-01-01
    “…Photomineralization of methane in air (10.0–1000 ppm (mass/volume) of C) at 100% relative humidity (dioxygen as oxygen donor) was systematically studied at 318±3 K in an annular laboratory-scale reactor by photocatalytic membranes immobilizing titanium dioxide as a function of substrate concentration, absorbed power per unit length of membrane, reactor geometry, and concentration of a proprietary vanadium alkoxide as photopromoter. Kinetics of both substrate disappearance, to yield intermediates, and total organic carbon (TOC) disappearance, to yield carbon dioxide, were followed. …”
