AbstractWe describe a fast and sensitive method for sequential speciation and separation of chromium(VI) and chromium(III) using dispersive magnetic solid phase extraction prior to determination by FAAS. The sorbent (mf-GO) was obtained by functionalizing a graphene oxide decorated with magnetite which was modified with triethylenetetramine. The sorbent was characterized by scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis, FTIR and elemental… CONTINUE READING
