Abstract:
Objective To ensure the reliability and accuracy of the data of the determination of iron in water. Methods The contents of iron in 177 water samples including well water, river water, steam water and tap water were determined by 1,10-phenanthroline spectrophotometry and atomic spectrophotometry.The effects of homogenous state and storage condition of water samples on the results of assay were analyzed ,the reason for the excessive iron in water samples was analyzed also. Results The rates of exceeding the standard were 5.08% for water samples untreated by well mixing during sampling and 31.64% for those treated by well mixing,there was significant difference between them(?2=39.87,P
