dcterms:description
Natural Na-montmorillonite (product of Southern Clay Product, Inc.) with the formula (Na 0,67 K 0,01 Ca 0,02)0,70 (Al 2,90 Mg 0,59 Fe 0,49 Ti 0,01)3,99 Si 7,92 Al 0,08)8 O 20 (OH) 4 was satureted with various amount of octadecylamine (NH2C18H37). The basal spacings d(00l) of natural Na-MMT and intercalated Na-MMt with the octadecylamine (ODA) were determined by X-ray powder diffraction (XRD) procedure. Theoretical XRD patterns of intercalated products were calculated using computer profile modeling program PROFA. The calculated set of basal diffraction for ODA molecules packed in Na-MMT as monolayer with d(001)=3,3 nm, d(002)=1,7 nm and d(003)=1,1 nm and as bilayer with d(001)=5,4 nm, d(002)=2,7 nm, d(003)=1,8 nm, d(004)=1,4 nm, d(005)=1,1nm were compared with observed data. The molecular modeling were used to present the detailed three-dimensional bilayer ODA/Na-MMT structure.
