Procedure for Fe determination

Start program 265 Iron, FerroVer to evaluate iron in the range from 0.02 to 3.00 mg/L Fe. It is required to swirl 10 mL sample and FerroVer Iron Reagent Powder Pillow in the cell to prepare the sample. After 3 minutes, fill another cell with 10 mL sample to prepare the blank. Clean the blank cell and install in the spectrophotometer or colorimeter. Remove the blank, clean the pretreated sample cell and insert in the instrument.
