“…Because of these advantages, a large number of researchers were used clay to adsorb several pollutants especially heavy metal ions from aqueous media (Rozic et al, 2000). Montmorillonite acts as a potential ionic exchanger for heavy metals because of its easy manipulation, high abundance, eco-friendly and harmlessness to the environment among natural clays (Chen et al, 2003;Bhattacharyya and Gupta, 2006;Orhan and Kocaoba, 2007;Abou-El-Sherbini and Hassanien, 2010;Vieira et al, 2010;Wu et al, 2011;Turan and Ozgonenel, 2013). Abou-El-Sherbini and Hassanien 2010used Na-montmorillonite clay as adsorbent to remove Cu(II).…”

Heavy metal pollution in the environment and effects on human health is within the most important issues. Because of continuous deterioration of water quality and persisting contamination level it has been observed and concerned by the scientists. Recently, to remove heavy metals from water/wastewater using various methods has been extensively studied. In conventional technologies, heavy metal removal/remediation is provided expensive because of non-regenerable materials used and high costs. Adsorption processes are being widely performed by several researchers for this purpose and various materials have been frequently used as adsorbent. It has been proved that adsorption is an effective method for purification, because of significant advantages including stability, utility, low-cost, ease of operation and performance. As adsorption technology is reduce the heavy metal ions concentrations to very low levels and because of using various low-cost adsorbent materials including biosorbents, clays, activated carbons, zeolites, metal oxides, it has major advantages. Metal adsorption onto adsorbent material, especially on agricultural wastes is a rather complex process because it is controlled by various factors. This process includes complexation, chemisorption, adsorption-complexation on surface and pores, micro precipitation, ion exchange. When used biological materials for adsorption process, some functional groups including sulphydryl, amido, hydroxyl and carboxyl, attach metal ions from water. This paper reviews the available adsorbent materials that have been used to heavy metal removal from water/wastewater and evaluates this technique advantages. Herein, the biosorbents such as banana peel, astragalus, chestnut sheel, natural adsorbents including clay also some artificial materials, like carbon-nanomaterials, zeolites, metal oxides, are reviewed as adsorbent materials for removal of different heavy metal ions like As(V), Pb(II), Cd(II), Cr(VI), Th(IV) and Eu(III) from water/wastewater.

“…Abou-El-Sherbini and Hassanien immobilized Na-montmorillonite clay with a 2-oxyhydrazino-N-(2-methylen-yl-hydroxyphenyl)pyridinium (OHMP) hydrazone derivative chelating agent to remove copper ions from spiked natural water and granite samples. 133 The intercalated clay possessed good chemical tolerance in acids, bases and common ionic species such as Na 1 , K 1 , Ca 21 , Cl À or SO 4 2À as well as good removal efficiency towards Cu(II) ions (119 meq per 100 g) at pH 6. They also found that the grafted MMT-clay also found potential application for the treatment of real contaminated effluent.…”

“…Nowadays, activated carbons, chitosan, natural zeolites and clay minerals are normally applied to remove heavy metals from wastewater [14][15][16][17]. Due to its higher adsorption e ciency and larger interlayer cation exchange capacities, richer extensive sources and lower cost, montmorillonite (MMT) is considered to be an important adsorbent to remove heavy metals from wastewater [18,19].…”

Montmorillonite-based porous adsorbent prepared by gel casting method was used to adsorb Cr(III)-organic complexes in tanning wastewater with the initial concentration of 10 mg L−1. The as-porous adsorbent exhibited an excellent performance of separation. Meanwhile, its structural and morphology were characterized by TG, BET, XRD, SEM, EDS and XPS, showing that the porous adsorbent was complete hollow ball structure. And the adsorption results showed that the adsorption amount of porous adsorbent rapidly declined from 9.58 to 5.28, and only Cr(III) was adsorbed, when the molar ratio of Cr(III) and citrate was more than 1:5. Increased of pH was beneficial to the adsorption of Cr(III)-citrate in range from 2.46 to 7.12. Furthermore, the best removal efficiency of porous adsorbent for Cr(III)-organic complex used up to 97% and remaining above 84% after five cycles. Finally, the adsorption mechanism of Cr(III) on porous adsorbent is also provided. Therefore, a kind of easy separated porous adsorbent was prepared in this study so as to treat tanning wastewater containing Cr(III)-organic complex following alkali precipitation, as well as solving the problem of difficult recycle.
