description: The theme of the final qualification work: Â«Wastewater treatment of oil and gas enterprises with nanocomposites of chitosan-graphene oxideÂ». This work is devoted to the development of a sorption material based on chitosan and graphene oxide for wastewater treatment. Tasks that were solved in the course of the study:Identification of the most effective components for sorbents. Development of a highly efficient sorption material based on chitosan and graphene oxide in two forms (plates and granules). Study of the sorption capacity of the material on model and real wastewater from the oil and gas industry. Development of two types of filters for the manufactured sorbent (domestic and industrial). The purpose of the master's thesis was the development of highly efficient sorption materials based on chitosan and graphene oxide for water purification and testing on real effluents from an oil and gas enterprise. The subject of this work is a nanocomposite consisting of chitosan and graphene oxide in two forms: plates and granules. The object - testing on model and real wastewater from an oil and gas complex enterprise of this SM is described in the experimental part of the work.In the course of the work, analytical methods were used to implement the creation of sorbents, methods of granulation and drying to create the sorbents themselves, as well as methods for studying wastewater: photometric and spectrophotometric analysis. Thus, the existing sorption materials for wastewater treatment from heavy metals were considered. It was found that it is most expedient to use organic materials for sorbents, such as chitosan and graphene oxide, since they purify water most effectively and do not harm the environment after their disposal. In the course of the work done, a sorption material based on chitosan and graphene oxide was created in two forms: plates and granules. High efficiency in relation to heavy metals has been proven: copper - 98%, manganese - 86%, total iron - 63%, zinc - 55%. Proposals have been made to improve the wastewater treatment system at an oil and gas enterprise. Household and industrial filters for the manufactured sorbent have been developed. The parameters of the developed adsorber were calculated for use in an existing installation at an oil and gas enterprise. The developed sorption material is promising for use not only on an industrial scale, but also in filters for post-treatment of running water. In addition, it is promising to use it with the developed universal household filter in field conditions.
