The absorption maximum of the Zr complex with pyrocatechin violet which lies at a wavelength of 550 m ation , makes it possible to determine this element in the concentration range 0.2 to I /ml, as opposed to the conditions prevailing at higher Zr concentration, when the absorption maximum shifts to 620 m ation . The precision of the method is about 3% while its sensitivity when used for determining this element in Ti and in TiF/sub 4/ is 0.003%. The Zr determination can be performed immediately after dissolving the alloy in HCl. The presence of Mo, Al, or Nb does not interfere. (TTT)
