| Abstract:A spectrophotometric method was established to determine the content of starch in paper. Starch was extracted by hot water, then the extract was reacted with iodine to form a blue-green colored complex,the absorbance of solution was measured at peak value of wavelength. This method has a good precision and rather high recovery. The detection limit is 0.02%. |
