Abstract

The invention discloses a preparation method for a recoverable adsorption microsphere for oil stains on a sea surface, which belongs to the field of treatment of oil stains on the sea surface. The method comprises the following steps: A, crushing cleaned shell to prepare shell powder; B, mixing the shell powder with silica sol and preparing a microsphere from the obtained mixture via a die, wherein the mass of the silica sol is 3 to 7% of the mass of the shell powder; C, calcining the microsphere at 200 to 450 DEG C for 20 to 50 min; and D, subjecting the calcined microsphere to surface modification so as to obtain the recoverable adsorption microsphere. The recoverable adsorption microsphere for treatment of oil stains on the sea surface has good floatability on the sea surface, can be recycled and does not cause secondary pollution.

Description

technical field [0001] The invention relates to the field of sea surface oil pollution treatment, in particular to a preparation method of recyclable sea surface oil pollution adsorption balls. Background technique [0002] The transportation of bulk petroleum and petroleum products mainly relies on sea transportation. During the loading and unloading process, oil products will inevitably leak, or even cause major accidents, which will pollute the ocean, especially the seawater in the port area, causing environmental impact and even ecological damage. To reduce the harm caused by this leakage and leakage, people have taken various remedial measures. At present, chemical reagent method and physical adsorption method are mostly used. The method of chemical reagent is mainly to use surfactant as oil displacement agent to disperse and dissolve free oil molecules in seawater through the action of surfactant. This method Although the efficiency is high, it actually causes deep po...
