Abstract
Abstract The aim of this project is to limit the pollutants Gelbstoff in Diyala River and its effect on Raman spectrum by using fluorescence and Raman technique . Many samples of river water were taken from different areas starting from Abu- Seda , Al Akheder , Swamrah region , Bohrez and mouth of river region in Tigris in south of Baghdad in Al - Rustamiah region where there was an increase in the pollutants as th ver runs towards the south . Besides , by taking some samples from the estuary of Diyala River , it was proved that the proportion of the pollutants in this region was higher than in Tigris . The peak of Raman spectrum ranges between [ 399-401 ] nm , and that Raman spectrum shift Auranges also between [ 3508.7 363307 ] cm and oscillator strength of O - H for H₂O molecule is between [ 687-737.4 ] N / m . These differences are due to the variation of the saltiness in different regions . All that results are correspondent according to literature .
