摘要：

This study focused on the potential to transform a waste, hydrated iron sulfate, into a useful product. The waste was generated from titanium dioxide production and from the surface treatment of steel. Its disposal is restricted by environmental regulations, and consequently, it has to be recycled and/or treated The described recycling was achieved through synthesis of potassium ferrate, which contains iron in a hexavalent state (Fe(VI)). The synthesis process was achieved in a rotary reactor at room temperature using chlorine as an oxidant. The efficiency of potassium ferrate synthesis was about 60%. This paper presents details of the kinetics of the potassium ferrate synthesis.
