| titleOfInvention | Fulvic acid-potassium chloride combined eluant, and preparation method and application thereof |
| abstract | The invention discloses a fulvic acid-potassium chloride combined eluant, and a preparation method and application thereof, relating to the technical field of restoration of heavy metal pollution in soil. According to the invention, humic acids with different qualities for restoring heavy metal cadmium polluted soil are dissolved in a 0.1m/L potassium chloride solution, a 0.1m/L sodium hydroxide solution is utilized to regulate the pH value to 11 or so to prepare a 0.05-1.00% humic acid solution, centrifugation is performed, and the separated solution is a fulvic acid-potassium chloride mixed solution; and the fulvic acid-potassium chloride mixed solution can be used as a combined eluant to elute the cadmium polluted soil. The chemical eluant used in the invention has the advantages of simple formula, obvious effect, strong operability, low application cost, high elution rate and high removal effect for cadmium ions in soil. The test indicates that the elution rate is optimal when the concentration of the eluate is 0.05%, the pH value is 4, the volume ratio of the eluant to the cadmium polluted soil is 10:1 and the elution time is 2 hours; and the eluate can not generate secondary pollution to the soil, and has an obvious supplementation action on potassium lost in the elution process. |
