Chemisorption of organic dyes on chrysotile
asbestos and the toxicity issue
an extremely useful natural resource, has been studied extensively mineralogically and for
industrial application. Its extraction from ores has been greatly improved with respect to
safety in the work place. In spite of that, there is a decisive effort in many countries
to ban its use on the grounds that it is a toxic substance. This action resulting in
drastic decrease in production and the possibility of destroying the industry. The
chelation of asbestos with organic dyes seems to be a promising way to abate its toxicity.
Dyeing can be done when the fibers are slurred in water at ambient conditions in the same
way as textile fibers.
