▎ 摘  要

NOVELTY - The solar driven biomimetic in-situ soil remediation apparatus comprises: at least one fluid capillary channel configured to draw in and transport an aqueous fluid from a contaminated soil by capillary action when in contact with the contaminated soil; and a solar absorber comprising a photothermal material loaded on a porous material, where the solar absorber is in fluid connection with the fluid capillary channel and is configured to generate heat under solar irradiation to accelerate evaporation of the aqueous fluid from the apparatus, and at least some of any contaminants from the contaminated soil that are drawn into the apparatus in the aqueous fluid are retained in the apparatus. USE - The solar driven in-situ soil remediation apparatus is used for removing contaminants from contaminated soil, where the contaminants include heavy metal ions, organic pollutants, endocrine disrupting chemicals (EDC) and particulate matter. ADVANTAGE - The solar driven in-situ soil remediation apparatus utilizes the solar absorber that generates heat under solar irradiation to accelerate evaporation of the aqueous fluid from the apparatus, where at least some of any contaminants from the contaminated soil that are drawn into the apparatus in the aqueous fluid are retained in the apparatus and utilizes the photothermal material, which is capable of generating heat at a temperature of ≥ 400° C, preferably ≯ 500° C. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a solar driven in-situ process for soil remediation, comprising: contacting at least one fluid capillary channel with a contaminated soil to draw in and transport an aqueous fluid from the soil by capillary action; exposing a solar absorber comprising a photothermal material loaded on a porous material and in fluid connection with the fluid capillary channel to solar irradiation to generate heat so that evaporation of the aqueous fluid is accelerated and contaminants from the soil are retained by the fluid capillary channel and/or the solar absorber.
