PREPARATION AND ACIDIC PROPERTIES OF IRON PHOSPHATES WITH SODIUM DODECYL-SULFATE

Abstract

: Iron phosphate was prepared from iron nitrate and phosphoric acid with sodium dodecyl-sulfate at various stirring hours. The chemical composition of the obtained samples was estimated from ICP and XRD measurements. Particle shape and size distribution were observed by SEM images and laser diffraction / scattering methods. Further, the catalytic activity was studied with the decomposition of the complex between hormaldehyde and acetylacetone. Samples heated at 600ºC indicated XRD peaks of FePO 4 . Iron phosphates heated at 200 and 400ºC works as a catalyst.
