Abstract

The invention discloses a preparing method for an oil-contamination adsorbing material, and belongs to the technical field of oil contamination governance. In the preparing method, ferroferric oxide is modified through N-beta(aminoethyl)-gamma-aminopropyl-trimethoxysilane, graphene oxide is subjected to the effect of glucose for preparing and reducing graphene foam, and the graphene oxide is frozen and dried to be subjected to hydrazine hydrate steam reduction to obtain vapor-phase-reduction graphene foam; flexible polyurethane foam serves as a base material, sodium alginate and polyethyleneimine solutions are added and applied to the surface of the flexible polyurethane foam, and are mixed into soaking liquid and quickly soaked into polyurethane foam, and the water-phase environment is shown in a three-dimensional open hole inside the polyurethane foam; due to the gravity effect and the capillary effect, water penetrates a foam base body, crude oil is separated on an oil-water-separator foam sample through the lipophobic property shown by the polyurethane foam after water is wet, the oil-water separation effect is achieved, and the good oil-water selectivity is achieved; the problems that an existing oil-contamination adsorbing material is small in adsorbing capacity and poor in oil-water selectivity are solved.

Description

technical field [0001] The invention belongs to the technical field of oil pollution control, and in particular relates to a preparation method of an oil pollution adsorption material. Background technique [0002] In recent years, with the acceleration of industrialization, the problems of oil pollutants and oil spills in water bodies have become increasingly prominent. According to analysis, 40% of the oil pollution in the water body comes from oil tankers and shipping such as oil tankers and oil tank leakage accidents, and 36% comes from urban sewage and industrial wastewater discharge. Oily sewage, waste liquid discharge and oil tanker and oil tank leakage will cause serious pollution to the environment. At present, most of the treatment of these pollution sources is to absorb the floating oil through oil absorbing materials to achieve the purification of the pollution sources. From the perspective of environmental protection, these oil-containing wastewater must be pr...
