The combination of oxalic acid with power ultrasound fully degrades chrysotile asbestos fibres.
The simultaneous action of power ultrasound and oxalic acid, as a chelating agent, rapidly converts chrysotile asbestos into water soluble material and a non-asbestos debris, not classifiable as hazardous under worldwide safety regulations.
