Starting with C12H250S03Na and C14H290S03Na surfactants as precursors, thermal analysis of the pure product
samples revealed that the final products were hydrated salt-like materials of the alkyl sulfate surfactants and the
transition metals with a composition of (CnH2n+lOS03-) 2M2+.nH20o r (CnHzn+10S03-)2M2022+'(nfHor2 M0 = Fe3+
