Abstract:
Some
physical and chemical parameters (water content, carbonate, pH,
Ca, Mg, SO4, P, Na, K, and some heavy metals) were
determined in sediment samples collected from El-Mex Bay, West
of Alexandria, Egypt. The load pollution index (PLI) was
calculated. Thermal gravimetric (TGA), differential thermal
analysis (DTA), infrared and X-ray diffraction were applied to
determine the mineral composition of sediments. Different
kinetic parameters (n, Ea, A, DH, DS, Tm and Z) were evaluated
and discussed.
Keywords: Marine sediments; Thermal analysis; TGA–DTA; X-ray
diffraction; El-Mex Bay, Egypt.
