ABSTRACT

The coordinating nature of the hydroxy carboxylic acids, such as tartaric and citric acids, has been utilized for the in-situ formation of anions representing the trivalent elements boron and aluminum and two dianions of the hydroxy acid selected under negative electrospray ionization mass spectral conditions. The abundance of these ions could be used for the quantification of boron and aluminum in water at concentrations ranging from 4.0 ppb to 535.0 ppb. For a period of six months, the validity of this method was tested with citric acid as the coordinating agent. Thus, the developed method offers a simple means for the quantification of boron and aluminum in water by negative electrospray ionization mass spectrometry with a single quadrupole mass spectrometer.
