摘要：
The transformation of ferrihydrite into goethite has been observed to be considerably facilitated under the conditions of oxidative hydrolysis of iron(II) sulphate. A probable scheme of the process mechanism has been put forward to explain the transformation that involves a step consisting of the formation of soluble complexes of ferrihydrite with ammonia.
