Title	Differential Titrimetric Determination of Bismuth
Author	Q. Won Choi, H. S. Lim
Keywords
Abstract	A precise EDTA titrimetric method involving a weight titration of major portion with solid reagent followed by titration of the remainder with a very dilute standard solution has been developed for the determination of bismuth. When the end point is determined by means of amperometry with a rotating mercury electrode, the error in bismuth analysis is less than 0.01 % even when Pb2+, Zn2+, or Cd2+ is present. However, copper interferes appreciably and masking with thiourea gives too low results.
