Method for testing impact of stirring time on removal rate of heavy metal chelating agent

The invention discloses a method for testing the impact of stirring time on the removal rate of heavy metal chelating agent, which comprises the following steps that: the heavy metal chelating agent is prepared for further use; copper ion solution is prepared; the heavy metal chelating agent solution is added in; supernatant is respectively taken out after the mixture is stirred for different time, and the absorbency of the supernatant is tested; the amount of the chelated Cu2+ is worked out; and the impact on the removable rate is obtained according to the amount of the Cu2+. According to the method for testing the impact of stirring time on the removal rate of heavy metal chelating agent, the impact of the stirring time on the removal rate of the heavy metal chelating agent can be quickly tested, the test precision is high, the test steps are simple, the test cost is reduced, and data bases are provided for the use of the heavy metal chelating agent.
