摘要：

The stability constant of ML2 species for the system lead + nitrilotriacetic acid (NTA) has been determined (log βML2 = 17.0 + 0.2) at 25°C in KNO3 0.1 M from polarographic measurements. The influence of this species was considered in speciation studies of lead in freshwater and seawater conditions, the competition of the Ca2+ and Mg2+ ions having been analysed. © 1990.
