Summary A determination of silicon is described which utilizes the selective extraction of molybdosilicic acid with methyl-iso-butyl-ketone. The extract is mixed with iso-propanol. No additional electrolyte is necessary because sufficient sulphuric acid is coextracted and provides good conductivity. The 3s-limit of detection was found to be 4×10−8 mol l−1 Si. The method was applied to determine silicon in cereals.
