Environmental crisis in the rural areas of developing countries is increasingly becoming an important cause of cross-border migration of population and South Asia is no exception to this phenomenon. Such movement of population in the Indo-Bangladesh context is generating a range of destabilising socio-political, economic, ethnic and communal tensions in India. It has embittered Indo-Bangladesh ...
متن کاملInfrared study of HDTMA+ intercalated montmorillonite.
In this paper, FTIR spectroscopy using attenuated total reflection (ATR) and KBr pressed disk techniques has been used to characterize sorbed water and HDTMA+ in organo-clay. Sorbed water content decreases with the intercalation of HDTMA+. With the decrease of the sorbed water content, the position of the nu2 mode shifts to higher frequency dramatically while the stretching vibration shifts to ...
متن کاملThe sedimentation capabilities of hexadecyltrimethylammonium-modified montmorillonites.
Natural montmorillonite was modified with a quaternary ammonium compound, hexadecyltrimethylammonium (HDTMA). The sedimentation capabilities of unmodified and modified montmorillonites were then investigated. The sedimentation velocity of modified montmorillonites increased if the amounts of adsorbed HDTMA were from 0.3 to 1.0 times the cation exchange capacitity (CEC). It also emerged that the...

متن کاملRegeneration of HDTMA-modified minerals after sorption with chromate anions
Surfactant-modified minerals have been widely used for the sorption of anionic and non-polar organic contaminants. This paper investigates the regeneration of various hexadecyltrimethylammoniun bromide (HDTMA)-modified natural minerals saturated with chromate anions using different solutions for the extraction of chromate that has been sorbed at optimum conditions. The examined minerals include...
