Preparation and modification of hybrid compounds based on GO-biochar and verification of their sorption properties

Popis výsledku v původním jazyce

Graphene oxide (GO) is a hydrophilic compound based on the oxidation of graphite in a sulfuric acid medium with strong oxidizing agents (KMnO4). Through oxidation, polar oxygen groups such as -OH, -C = O, -COOH epoxy are introduced into the carbon structure. Their introduction gives reduced graphene oxide (rGO) and, depending on the reaction conditions and the type of reducing agent, graphene with certain defects in the carbon structure is also obtained. GO chemistry finds many applications in the environmental field (adsorption of pollutants in water), in the biomedical field (antibacterial, antiplatelet and antitumor effects), in the electrical field (Li-batteries, supercapacitors), and in the material field (bone cement, composite compounds) etc. This paper briefly describes the basic information about one of the most important carbon nanocompounds - graphene oxide. At the same time, it examines how the method of processing the input suspension influences the thermal properties of GO-Biochar, the contact product GO with biochar, the effort to spin GO, and the sorption capacity of compounds based on GO and biochar against phenol from phenolic waters and other selected substances. The results of the performed experiments show that the adsorption capabilities of biochar are improved when it is modified (Biochar has sorption capacity in case of phenol water 89.90 mg/g compared to the adsorption product of Biochar on GO which has sorption capacity in case of phenol water 111.60 mg/g).
