In this article we will discuss about:- 1. Composition of Clay Minerals 2. Isomorphous Substitution 3. Properties of Clay Minerals. Composition of Clay Minerals: Clay minerals in soils belong to phyllosilicates group of minerals, which in turn belong to silicate minerals. Silicate minerals make up about 90% of the rock-forming minerals of the earth's crust. The word Phyllon in the [...]
In this article we will discuss about:- 1. Principle of Infrared Spectroscopy 2. Equipment of Infrared Spectroscopy 3. Types 4. Sample Preparation 5. Uses and Applications. Principle of Infrared Spectroscopy: IR spectroscopy works on the principle that molecules absorb specific frequencies that are characteristic of their structure. At temperatures above absolute zero, all the atoms in molecules are in continuous vibration [...]
