Preparation of Ammonium Iron Blue from Copperas and Ammonium Sulfate Wasted Liquid

Article Preview

Abstract:

Ammonium iron blue was prepared with ferrous sulfate and ammonium sulfate wasted liquid, ferrous sulfate is a byproduct from titanium dioxide production, and ammonium sulfate waste liquid is produced by ammonia oxidation iron oxide red. The influence of some parameters such as n (FeSO4)/n (Na4Fe (CN)6) ratio, PH value , reaction time, reaction temperature were discussed. The total iron content of ammonium iron blue is 35.89% and the quality of ammonium iron blue was accorded with the industrial standard (HG/T 3001-1999). SEM experimental result proved that the particle size of ammonium iron blue was uniform and about 100-200nm, and the structure of ammonium iron blue is Straight edges polyhedron. XRD experimental result showed that the structure of ammonium iron blue was similar to Fe [Fe (CN)]3.
