The use of ultra filtration in trace metal speciation studies in sea water
During this work, size fractionation technique “ultra filtration” is used in speciation studies of trace elements in the coastal sea water. Filtration is the most commonly used method to fractionate trace metal species, but often only “dissolved” and “particulate” fraction. The purpose of the presen...

| description | During this work, size fractionation technique “ultra filtration” is used in speciation studies of trace elements in the coastal sea water. Filtration is the most commonly used method to fractionate trace metal species, but often only “dissolved” and “particulate” fraction. The purpose of the present study is to determine colloidal and suspended particulate concentrations of Fe, Zn, Cu, Ni, and Mn in sea water. Suspended particulate matter were separated in three different size groups namely (>2.7 μm, 0.45 μm and 0.22 μm) by suction filtration using cellulose acetate and nitrate filter membranes.
