Abstract A new indirect absorptiometric method for boron, based on the fluoride complexes of molybdate and boric acid has a molar absorptivity of 7000 and a determination range from 0.1 to 2.5 mg of boron per 50 ml. The method is subject to interferences from elements forming strong fluoride complexes or heteropoly acids. If the method is used with the methyl borate separation technique, all these interferences are eliminated. The variables affecting the method were investigated, and the optimum working conditions determined. (auth)
