[0022] figure 1 It is the ultraviolet absorption spectrum diagram of chelating agent and different metal ions. In order to explore the selectivity of the chelating agent to aluminum, lead, and cadmium ions, use a 1cm cuvette to pipette 3mL of the ethanol solution of the chelating agent into the cuvette each time, and add 0.05mL, 1×10 -2 mol / L metal ion (Zn 2+ , Mg 2+ 、Cr 3+ , Fe 3+ , Mn 2+ 、K + 、Ni 2+ 、Sr 2+ 、Al 3+ 、Ag + , Hg 2 + , pb 2+ 、Cu 2+ 、Cd 2+ ) salt solution, observe the changes of its UV-vis, its ultraviolet spectrum except aluminum, lead, cadmium ions, in the presence of other metal ions, the ultraviolet absorption of the chelating agent basically does not change. Therefore, it has good selectivity to these ions.
