Disulfiram compositions based on biopolymers with graphite materials

Based on the bibliometric analysis of scientific publications, patents, Internet resources and previously published results of our own research, the feasibility of developing a new disulfiram composition based on graphite materials with biopolymers was substantiated. Optimal methods were selected and samples of OG-A-DS (graphene oxide-albumin-disulfiram) nanocompositions were obtained in the form of an aqueous dispersion, as well as samples of TRG-BP (thermally expanded graphite-biopolymer) compositions, which will be potential carriers for drugs.

Adsorption Desulfurization of Simulated Diesel Fuel Using Graphene Oxide

Graphene oxide (GO) was synthesized from graphite powder by the improved Hammers method and used for the adsorption of organosulfur compound (dibenzothiophene, DBT) from model diesel fuel. FT-IR spectroscopy, X-ray diffraction, SEM, EDX, and BET were used to characterize the GO. Several factors, such as solution pH, initial DBT concentration, adsorption contact time, adsorption temperature, and adsorbent dosage were used to test the DBT removal efficiency.
