IPC: G01N31/02
Filed: 2007-03-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide an analytic method for accurately analyzing a concentration of a free hydrofluoric acid in an aqueous solution containing the hydrofluoric acid and a silicon compound generated by solving glass and metal silicon so as to correctly determine a solution capability of the aqueous solution.  <P>SOLUTION: After the silicon compound in the aqueous solution containing the silicon compound and the hydrofluoric acid is removed by a means for separating the silicon compound as a hexafluoro silicate, the concentration of the hydrofluoric acid is measured. Additionally, the concentration of the hydrofluoric acid is measured without separating the silicon compound as the hexafluoro silicate. The former measurement value is corrected by using the latter measurement value.  <P>COPYRIGHT: (C)2008,JPO&INPIT
