title: Photometric titration of small quantities of metals with ethylenediaminetetra-acetic acid.
abstract: A commercially available photometric titration apparatus has been used for the determination ofAl, Ba, Bi, Ca, Cd, Co, Mg, Mn, Ni and Zn in the 4-20 mug range and of Hg in the 16-32 mug range. Pooled standard deviations (32 determinations) of between 0.09 and 0.15 mug were found for all the metals except Ba (0.20 mug) and Hg (0.44 mug, 24 determinations).
