摘要
Forced hydrolysis of Fe(III) ions in acidic media was performed under controlled synthetic conditions to produce alpha- and beta-FeOOH iron oxides. The forced hydrolysis synthesis was carried out, separately, in an aqueous medium and the lamellar lyotropic liquid crystalline phase of a commercial non-ionic surfactant/water system. The FT-IR analyses confirmed formation of alpha- and beta-FeOOH iron oxides in the aqueous and the surfactant media with slight formation of ferrihydrite and haematite. TEM micrographs have shown that particles formed in the lamellar lyotropic phase are smaller than those produced in the aqueous medium with their smallest size dimension being constrained in the nanometre scale with a size ranging between 5 and 100 nm. Particles produced in the nanoscale size appeared to have different optical properties compared to their counterparts produced in the microscale size.
