Adsorbent material with multiple functions for petroleum hydrocarbon pollutants and preparation process

Abstract

The invention discloses an adsorbent material having a plurality of functions for petroleum hydrocarbon contaminants, and a preparation process of the adsorbent material. The preparation method of the adsorbent material comprises the steps: preparing a mixed solution F from NH4HCO3, Ca(NO3)2, (NH4)2HPO4, a urea aqueous solution and a calcium sodium edetate dihydrate solution; preparing a mixed solution G from a poly(beta-polyhydroxybutyrate) chloroform solution and a polyethylene glycol chloroform solution; adding dropwise the mixed solution F to the mixed solution G to obtain a mixed solution H; adding dropwise the mixed solution H to a polyvinyl alcohol solution to obtain a mixed solution I; and adding the polyvinyl alcohol solution to the mixed solution I and then centrifugally separating, and freeze-drying to obtain the adsorbent material having a plurality of functions for petroleum hydrocarbon contaminants. The adsorbent material having a plurality of functions for the petroleum hydrocarbon contaminants, which is disclosed by the invention, is simple in fabrication process; the obtained adsorbent material has a phosphorus controlled-release function and a function of adsorbing the petroleum hydrocarbon, and also has biodegradability.

Description

technical field [0001] The invention belongs to the technical field of treatment of water bodies polluted by oil spills, and in particular relates to an adsorption material with multiple functions for petroleum hydrocarbon pollutants and a preparation process. Background technique [0002] In recent years, with the increasing demand for oil and its products in various countries around the world, oil spill accidents have occurred frequently in the process of offshore mining, loading and unloading, transportation and utilization of oil, which not only caused a large amount of crude oil loss, but also caused serious pollution to the environment. It is increasingly threatening the ecological environment of water bodies and land areas, and has long-term harm to water body environment, natural resources and aquaculture resources. Therefore, oil spill pollution in water bodies has become a major environmental problem that people must face. [0003] At present, there are mainly phys...

Problems solved by technology

In order to further popularize and apply the technology of combining physical adsorption and immobilized microorganisms for enhanced degradation in the treatment of oil spill pollution in water bodies, it is necessary to develop materials with both slow-release phosphorus and physical adsorption-biodegradation of petroleum hydrocarbons. This is of great significance for improving the efficiency of oil spill pollution treatment in water bodies and reducing environmental pollution, but there is still a lack of technology and research reports in this area
