- Abstract
Owing to phytoremediation in heavy metal contaminated soil takes time long, and is easily affected by heavy metal,its application in sudden heavy metal contaminated soil events stiil faces challenges. This study provides a resin-plant combined remediation method, resin can inhibit the migration of heavy metals in the soil for a short period of time,protect the initial growth of plants,and then the heavy metals can be slowly released and adsorbed by the remediation plant, ultimately heavy metal can be removed from the soil. It can be noted that after adding 0. 5% resin,the concentration of soluble Cu2+ and Zn2+ in the soil decreased by 50. 02% and 83. 41%,it also promoted the retention of soil moisture and the improvement of soil pore structure. When the resin was added for 15 d,the concentration of Cu and Zn in the roots of water spinach were only 39. 48% and 31. 53% of those without resin addition, and the growth of water spinach at this time was obviously better than no resin group. This study aims to provide a reference for the phytoremediation of soil pollution by heavy metals.
