Preparartion and characterization of terbium over paligorsquite clay as acid catalyst
Palygorskite clays containing 5% and 10% terbium (W/W) were prepared by ion exchange from acid-leached naturalclay. Samples were calcined at 523, 573, 623 and 673 K to verify the e ect of the temperature over the physical±chemicalproperties. Characterization was using X-ray di raction, infrared spec...
