    A method for determining silicon content in nodulizer includes using nitric aid and hydrofluoric acid to dissolve test piece for preparing weak acid test piece solution, adding ammonium molybdate into said test piece solution to make monolecular silicic acid and ammonium molybdate be complexed for forming yellow SiMo heteropolyacid, using chemicals to interfere it then using ammonium sulfate to reduce SiMo heteropolyacid to be SiMo blue being used to detect its absorbance.
