Abstract
Montmorillonite is a layered aluminosilicate mineral and is a natural nanostructured material. At present, montmorillonite is widely used in polymer composites. With cation exchange, water absorption, dispersion and other functions are widely used. However, the surface polarity of montmorillonite is large and the compatibility with the polymer is poor, so it needs to be modified to be better dispersed in the polymer matrix. In this paper, the methods of organic modified montmorillonite and the adsorption properties of modified montmorillonite are discussed.
Highlights
Montmorillonite is a layered aluminosilicate mineral and is a natural nanostructured material
Montmorillonite modification method can be divided into three kinds of general: inorganic modification, organic modification and inorganic/organic compound modification, the most commonly used organic modification [4]
The results show that the adsorption effect of montmorillonite after organic modification is better, the main mechanism of adsorption is surface adsorption, organic modified montmorillonite is distributed and adsorbed
Summary
Montmorillonite has a good ion exchange, adsorption capacity, and affordable, storage capacity, pollution-free features, is widely used in chemical, petroleum, transportation, environmental protection, food, medicine, energy and other industries, known as for "omnipotent material". In order to meet the practical needs of all walks of life, especially heavy metal wastewater treatment, the need to improve the quality of montmorillonite and its efficiency, so montmorillonite to be modified. Montmorillonite modification method can be divided into three kinds of general: inorganic modification, organic modification and inorganic/organic compound modification, the most commonly used organic modification [4].
