BORON DESORPTION IN SOME CALCAREOUS SOILS OF NINEVEH GOVERNORATE / NORTH OF IRAQ
The investigation was conducted to study the behavior of boron desorption in three calcareous soils, classified as calciorthid. The experiment of boron sorption was conducted by using a different concentrations (0,0.5,1,2,4,6,8,10,20) mg B.L-1 (as boric acid) at 298ْ k while desorption experiment wa...

| Summary: | The investigation was conducted to study the behavior of boron desorption in three calcareous soils, classified as calciorthid. The experiment of boron sorption was conducted by using a different concentrations (0,0.5,1,2,4,6,8,10,20) mg B.L-1 (as boric acid) at 298ْ k while desorption experiment was conducted from adsorbed soils by using (0.01) M CaCl2 at (289 ْ k ) in order to study of boron hystersis. Langmuir model was used to describe capability of boron adsorption / desorption then the desorption index was calculated. Obtained results showed that boron adsorption energy was (0.843-0.069) L. mg -1 while boron desorption energy was ( 10.037-22.683) L. mg-1, while the boron desorption index was ( 1.32 - 3.66) for this reason the boron adsorption was not reversible. |
