Determination of Metal Elements in Montmorillonite by AAS

Introduction

Various ceramic materials are widely used in many fields and include oxides, silicates and their minerals as well as clay minerals. Montmorillonite is one of the clay minerals produced in mass in Japan in the form of the naturally occurring bentonite and it is widely used as an absorbent, catalyst and casting binder, among others. It is a feature of montomorillonite that its thermal property varies with the content of Fe and Mg. Here are shown examples of determination of Fe, Mg and Al, another principal component, in montmorillonite.
