“…It is considered as the most important environmental component not only for the geo-chemical sink for contaminants but also acts as a natural buffer by controlling the transport of chemical elements and substances. Among the anthropogenic contaminants, heavy metal ions play a major role because of their persistence and toxicity (Iqbal and Shah 2011;Nabi et al 2010). The leaching of metal ions from the soil to surface water, groundwater, sea, plants, and other organisms depend on the potential mobilization of the metal ions.…”

The present study deals with possible contamination of the soil by metal ions which have been affecting the environment. The concentrations of metal ions in 14 borehole samples were studied using the ICP-OES standard method. The degree of contamination was determined on the basis of single element pollution index (SEPI), combined pollution index (CPI), soil enrichment factor (SEF), and geo-accumulation index (Igeo). Geo-accumulation indices and contamination factors indicated moderate to strong contaminations for eight boreholes (BL-1, BL-2, BL-6, BL-8, BL-9, BL-10, BL-12, and BL-13) while the rest were extremely contaminated. Among all the boreholes, BL-3 and BL-11 demonstrated the highest level of Cd(II) and Pb(II) which were found the most polluted sites. The level of metal contamination was also compared with other countries. The development, variation, and limitations regarding the regulations of soil and groundwater contamination can be provided as a helpful guidance for the risk assessment of metal ions in developing countries.

“…Various organic-inorganic type composite cation exchange materials have been developed by sol-gel methods in different laboratories [1][2][3][4][5][6][7][8][9][10][11][12][13]. However, special attention has been given in our laboratory for synthesis and characterization of ion-exchange stationary phases by the incorporation of electrically conducting as well as non conducting polymers into inorganic ion-exchangers to create new 'organic-inorganic' composite cation-exchanger stationary phases suitable for column operation during wastewater treatment [14][15][16][17].…”

“…The attempt has been made by various researches to improve the chemical, mechanical, thermal properties and selectivity of composite ion exchangers for certain heavy metal ions (Islam and Patel 2008;Nabi and Naushad 2008;Bushra et al 2012;Nabi et al 2011;Khan and Paquiza 2011). The composite ion exchangers have been used effectively in different fields such as ion selective electrodes, catalysis, hydrometallurgy, bimolecular separations, chromatography and environmental science engineering (Hassan et al 2001;Nabi et al 2010;Arrad and Sasson 1989).…”

Pectin-cerium (IV) tungstate composite (Pc/ CT) has been prepared by sol gel method at room temperature. The composite ion exchanger has been characterized using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy and Fourier infrared spectroscopy. The ion exchange capacity, pH titrations, thermal stability and distribution coefficient of composite ion exchanger were investigated. The Na ? ions exchange capacity of the Pc/CT has been observed higher (1.4 meq g -1 ) as compared to its inorganic counterpart (0.8 meq g -1 ). Pc/CT composite ion exchanger was thermally stable and retained about 60 % of its ion exchange capacity up to 400°C. The distribution study has inferred more selective the Pc/CT for Zn 2? as compared to other metal ions. The adsorption efficiency of Pc/CT was tested for methylene blue removal dye from aqueous phase. The removal of dye followed pseudo-second-order kinetics.
