Effect of heating on palygorskite and acid treated palygorskite properties

open access: yesSurface Engineering and Applied Electrochemistry, 2008
The behavior of palygorskite as an adsorbent or catalyst support is governed mainly by the magnitude of its surface areas and degree of surface activity. Most heterogeneous catalytic reactions take place at elevated temperatures. It is important and necessary to known the possible changes in the physicochemical properties and hence the catalytic ...

Experimental studies with palygorskite dusts. [PDF]

open access: yesOccupational and Environmental Medicine, 1987
As the preliminary results of experimental studies on dust from the palygorskite group have led to some confusion a detailed description of the completed investigation is given for clarification. As in other experiments the biological effects have been shown to be associated with the physical characteristics of the fibres in these specimens. Samples of
