تقييم هذه الدراسة أشكال المنغنيز الكيميائية و توزعها في ترب مختارة من مختارة من محافظة حمص. استخدمت مخططات الاستخلاص التسلسلي لتجزئة المنغنيز إلى الشكل المتبادل المرتبط بالكربونات, المرتبط بأكاسيد الحديد و المنغنيز, المرتبط بالمادة العضوية, و الشكل المتبقي.
This study was undertaken to
evaluate the chemical speciation and distribution of Mn in soils of
Homs Governorate. Sequential extraction scheme was used to
fractionate Mn into exchangeable, bound to carbonate, bound to
manganese (Mn) and iron (Fe) oxide, organically bound, and
residual forms.
