المعايير الثيرموديناميكية و استخدامها في دراسة مياه المصب العام

Abstract EN

Provide massive amount of main out fall water that increase salinity little or a lot about the permissible limits requires finding techniques by which the use of this water with less deterioration as possible to the chemical and physiochemical characteristics of the soil through the expense of same thermodynamic criteria such as activity, ion pairs and free ions and the express actual concentrations more accurately than analytical concentration.

In order to peruse the objective, Seven location were selection, ( Mahmodia, Al-Swaria, Al-Mamra, Al-Shomaly, Trance control, Al-Dalmage channel, Al-Shalala ) the research has been done in order to study-The sequence of ion pairs in Main Out Fall Water was found as follows : ( MgSO4 ) o> ( CaSO4 )o> ( NaSO4 )-> ( MgHCO3 ) + ( CaHCO3 ) + > ( KSO4 )-And the concentration of the free ions was in the following order : Na + >SO4-2Mg + 2>Ca+2>HCO3->K + But the ionic activity was in the following Order Na + >SO-2>Mg + 2>HCO3->Ca + 2>K+ correction of ion pair and ionic activity increased adsorption ratio (SAR) values in the rate ( 3.43-13.24 ) and the values ( SARi ), ( SARa ) between ( 3.9-15.4 ), ( 4.5-18.7 ) respectively.

- Correction of ion pairs and ionic activity increased the adjusted adsorption ratio ( Adj.RNa ) values in the rate of ( 3.63-14.6 ) and the values ( Adj.RNa* ), ( Adj.RNa** ) between ( 4.05-16.70 ), ( 4.51-18.7 ) respectively.
