ABSTRACT
Analytical chemists have long used statistical methods to help them
organize and interpret experimental data, especially where large
numbers of these are generated, as well as to help them design
new experiments. Recently chemometrics has found applications in
wider fields, such as the determination of the geographical origin
of food and other products. During the past several years, we have
carried out a systematic study of the factors affecting the pore struc-
ture and surface chemistry of cerium oxide and of mixed oxides
of cerium with various transition metal or alkaline earth metal
ions.
