Abstract

A support material is suspended in a solution of ferromagnetic material comprising Fe (II), which is pptd. exclusively the support, as a hydroxide or insoluble salt, by the gradual and homogeneous formation of OH circled negative ions in the solution. The OH circled negative are introduced by gradually adding an alkaline solution to the suspension with vigorous agitation.
