| titleOfInvention | A rapid screening method for heavy metal passivators |
| abstract | The invention relates to a rapid screening method for heavy metal passivation agents, which comprises the following steps: adding a test passivation material into a heavy metal solution, taking the treatment without the passivation material as a control, filtering after mixing, and measuring the heavy metal content in the filtrate; If the heavy metal content is lower than the control, it is preliminarily considered that the material has a passivation function; then, the passivation material is mixed with the heavy metal contaminated soil, and the treatment without the passivation material is used as a control, and the reactant is added to react for a certain period of time, and then the extraction is added. If the heavy metal content is lower than the control, it can be determined that the material has passivation function; this method can quickly and accurately screen out metal passivation agents suitable for heavy metal soil, and screen metal passivation The agent cycle is short, the operation is simple, and it can meet the needs of the current soil remediation work. |
