Determination of Total Acid in Palygorskite Chemically Modified by N-Butylamine Thermodesorption

The acid properties of palygorskite clay (R1) were studied using n-butylamine as probe molecule. A comparison was made of these properties in palygorskite clay (R1), in an acidified palygorskite (R2) and in acid palygorskite loaded with 2% of lanthanum (R3). The total acid properties were determined...
