Facile synthesis of novel nanocomposite composed of CoO, MgO, and MgBO for malachite green dye decontamination from aqueous media.

Malachite green is a hazardous chemical that poses serious threats to aquatic ecosystems due to its toxicity and persistence in the environment. Additionally, it is harmful to human health, recognized as a carcinogenic and mutagenic agent that can cause long-term adverse effects. Hence, in this study, malachite green dye was efficiently removed from aqueous media using CoO/MgO/MgBO novel nanocomposites, known as CBM600 and CBM800.

Simplified synthesis and identification of novel nanostructures consisting of cobalt borate and cobalt oxide for crystal violet dye removal from aquatic environments.

Crystal violet dye poses significant health risks to humans, including carcinogenic and mutagenic effects, as well as environmental hazards due to its persistence and toxicity in aquatic ecosystems. This study focuses on the efficient removal of crystal violet dye from aqueous media using novel CoO/Co(BO) nanostructures synthesized via the Pechini sol-gel approach. The nanostructures, which were abbreviated to EN600 and EN800, were fabricated at calcination temperatures of 600 and 800 °C, respectively.
