| titleOfInvention | Soil heavy metal activator and preparation method and application thereof |
| abstract | The invention discloses a soil heavy metal activator and a preparation method and application thereof. The soil heavy metal activator comprises an active ingredient, wherein the molecular structure of the active ingredient at least contains one amidoxime group and one amino group, or at least contains one amidoxime group and one amino group. The preparation method of the soil heavy metal activator comprises the following steps: heating hydroxylamine hydrochloride and one or more compounds containing cyano and amino or cyano and amino in the presence of sodium carbonate and alkali to 60-85 ℃, reacting at constant temperature for 3-5 hours, cooling to room temperature, and adjusting the pH to 6-8 to obtain the heavy metal activator. The soil heavy metal activator is added into the heavy metal contaminated soil according to the mass ratio of 0.1-20 per mill of the active ingredients to the soil, so that the aim of activating the soil heavy metal can be fulfilled. The invention can efficiently activate pollution factors such as copper, lead, zinc, cadmium, nickel, mercury and the like in soil, has good activation effect and no secondary environmental risk. |
