Abstract: Disclosed is a method of removing volatile organic compounds from sponges by using supercritical/subcritical fluid, The method includes the following steps: placing the sponge block to be treated in the extraction kettle; feeding the critical flow medium into the extraction kettle; performing extraction under the supercritical or subcritical conditions of the critical flow medium; releasing pressure to normal pressure after extraction; and separating to obtain devolatilized sponge. The volatile removal device used in the disclosure is a supercritical extraction equipment, which can adopt static extraction or dynamic extraction or a combination of the two. CO2 releases pressure in the separating kettle after contacting the sponge to be treated in the device for mass transfer for a certain period, when the static extraction devolatilization is carried out.
