Photometric titration of metal ions, based on ultraviolet absorption by a lead(II) complex. I: Determinations in alkaline solutions
Mikrochimica Acta（1971）
摘要
A method is described for the complexometric determination of alkaline earth metals with EDTA and EGTA by means of photometric end-point indication at 242 nm, using lead(II) as indicator ion. Determinations of 10−5M solutions of calcium and barium appeared to be possible with good accuracy.
