Determination of Iron in the Industrial Waste Water by Spectrophotometry

XUAN Ya-Wen WU Wen(Department of Chemistry,Zhoukou Normal University,Zhoukou,Henan 466001,P.R.China)  
The determination of iron in the industrial waste water was investigated by spectrophotometry with 1,10-phenanthroline,according to method for determination of trace iron.The method is simple,fast and accurate.The iron in the industrial waste water exists in the form of Fe3+,with hydroxylamine hydrochloride to Fe2+.Fe2+ and 1,10-phenanthroline can formed a colored compound which can be determined by spectrophotometry.The effects of maximum absorption wavelength,coloration time,pH value on determination result were discussed in actual mechanical process,and iron determination was finished after determination of the optimal experimental conditions.The result is satisfied.
