| Abstract: | The EDTA titrimetric method, the sulfosalicylic acid-photometric method and the AAS method were applied to the determination of iron in nano-iron oxide sol. As shown by the analytical results obtained by these method, the EDTA titration method and the SSA-photometric method had their accuracy and precision comparable to the AAS method, and were suitable to be used as control method in routine analysis to inspect the quality of nano-iron oxide sol and as a guide for the optimization of the process of the preparation. |
