Abstract

ABSTRACT

 

  This study was conducted to investigate mineral composition of the Tigris River sediments in the province of Baghdad and its impact on the adsorption and release of nickel ten areas were selected for the study  It extends from Al-Rashidiya in the north to Al-Mada'in in the south  soil samples were taken from within the waterway and a mineral analysis of those sediments was conducted for three areas: the beginning, middle and end of the river in Baghdad Governorate, and the results showed the presence of Variation in the nature of the mineral composition, as the presence of the mineral of smectite, palygoriskite and mica minerals of both types of triple- and diocta (biotite and muscovite) was observed in the presence of real chlorite minerals and mica trioctahydra biotite in the clay models of those soils. and the results of the nickel adsorption and release experiment showed a decrease in the values of the binding energy and the maximum adsorption at the beginning of the study area, reaching 2.70 ml and 437.4 µg Ni+2 respectively in where they increased at the end of the study area to 5.55 mg-1 and 1162 µg Ni+2.
