| titleOfInvention | Method for concentrating soil heavy metals of sewage irrigation area by coalition of composite restoring agent and festuca arundinacea |
| abstract | The invention discloses a method for concentrating soil heavy metals of a sewage irrigation area by coalition of a composite restoring agent and festuca arundinacea, wherein the composite restoring agent consists of a chelating agent nitrilotriacetic acid (NTA) and a surfactant sodium dodecyl sulfate, wherein the mol ratio of the chelating agent nitrilotriacetic acid to the surfactant sodium dodecyl sulfate is (5-15) mmol.kg＜-1＞:1mmol.kg＜-1＞. Experimental results show that a most remarkable effect of increasing the content of Cd in the festuca arundinacea is achieved due to the addition of the surfactant and the chelating agent, the concentration of the heavy metals can be promoted through co-addition of the surfactant and the chelating agent, and especially the effect is more remarkable when 5 mmol.kg＜-1＞ of the NTA and 1 mmol.kg＜-1＞ of the chelating agent or 10 mmol.kg＜-1＞ of the NTA and 1 mmol.kg＜-1＞ of the chelating agent are used for restoring sewage irrigation soil. |
