| Abstract: | In recent years,the comprehensive management of soil pollution and remediation has become a re-search hotspot in the field of environmental protection.Photocatalytic technology which is used to remedy polluted soil is an emerging technology with easy operating,low cost,no secondary pollution and has broad development prospects. The principles of remedying soil pollution by photocatalytic technology are analyzed,and research progresses of photo-catalytic materials in soil organic pollutants (pesticides,aromatic and petroleum etc.)degradation and heavy metal ions (Ag+ ,Cr6 + etc.)reduction photocatalyzed by nano-TiO2 are reviewed.Besides,development direction and sug-ession for the future are also pointed out. |
