摘要

以硝酸铁和磷酸为原料，用十二烷基硫酸钠在不同搅拌时间下制备磷酸铁。所得样品的化学成分由ICP和XRD测量估计。采用扫描电镜(SEM)和激光衍射/散射方法观察颗粒的形状和尺寸分布。进一步研究了甲醛与乙酰丙酮配合物的催化活性。样品在600℃下加热，XRD峰为fepo4。在200和400℃下加热的磷酸铁可作为催化剂。

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

: 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.
