Abstract
This invention pertains to an improved method of inhibiting peroxide-reduction catalytic activity and concomitant toxicity of asbestos and nonasbestos iron-containing silicates. These undesirable reactions can be substantially reduced or essentially eliminated by contacting these potentially harmful materials with an aqueous solution comprising a non-mutagenic non-toxic iron chelating agent, such as phytic acid, diethylenetriamine pentaacetic acid (DTPA) or derivatives of these.
