“…The high ion exchange capacity of zeolites, their extensive porosities and specific surface areas, as well as their relatively cheap prices, make natural zeolites attractive adsorbents [208][209][210][211][212][213][214][215][216][217][218][219][220][221][222]. However, synthetic zeolites are also widely tested, especially because through synthesis a useful control can be obtained over the Si/Al ratio in the zeolite composition.…”

“…However, surface modification can change the surface functionality by adding cationic surfactants or other hydrophobic groups thus making them applicable for adsorption of various anions and organics. The most common surface modifiers are salts of a variety of quaternary amines such as hexadecyltrimethylammonium (HDTMA, the most popular surfactant) [210][211][212][213][214]224,226,[234][235][236], octadecyldimethylbenzylammonium (ODMBA) [216][217][218], stearyldimethylbenzylammonium (SDBA) [219,224] or benzyltetradecyl ammonium (BDTDA) [212]. Other posibilities are cetylpyridinium salts [211,220], cyclodextrins [208] and chlorosilanes [209].…”

“…The most promising and economical approach for detoxifying feedstuffs is the addition of nutritionally inert mineral adsorbents to animals diets to decrease the bioavailability of the mycotoxins during absorption in the gastrointestinal tract thus preventing uptake into the blood and subsequent distribution to organs. [3,4] They can be recommended when all the prevention rules fail and, consequently, farmers suspect that feed has been contaminated with mycotoxins. [5] Of the mycotoxins found in feedstocks, considerable attention has been given to fumonisins because on one hand they are the most diffuse toxins in farm feedstuff; on the other hand they cause leukoencephalomalacia (LEM) in horses and pulmonary oedema in pigs.…”

“…Promising results in binding FB 1 were obtained using organically modified adsorbents such as organozeolites [15] , which had previously been successfully tested for the binding of aflatoxin B 1 , zearalenone, ochratoxin A and the ergopeptine alkaloids. [4,16,17] Modified clays or organoclays are prepared from natural clays, generally montmorillonite, by exchanging the inorganic cation with an ammonium organic cation. Modified clays are also effective sorbents for a variety of organic and inorganic contaminants.…”

The most promising and economical approach for detoxifying mycotoxins contaminated feedstuffs is the addition of nutritionally inert mineral adsorbents to animals diets to decrease the bioavailability of the mycotoxins during absorption in the gastrointestinal tract thus preventing uptake into the blood and subsequent distribution to organs. Many adsorbents, mainly activated carbon and clay minerals exhibit a high ability to bind most of the mycotoxins. On the other hand, adsorbents for fumonisins have been tested in only a few cases, though these mycotoxins are toxic to number of animal species. This study reports an investigation on the ability of organically modified clays to bind fumonisins B 1 (FB 1 ) and B 2 (FB 2 ). Organically modified clays are commercial materials prepared from natural clays, generally montmorillonite, by exchanging the inorganic cation with an ammonium organic cation. A screening experiment conducted on 13 organically modified clays and 3 non modified clays, used as controls, has confirmed that the presence of an organic cation in the clay interlayer promoted the adsorption of both fumonisins. On the basis of the results of the screening test, four modified clays and a Na-montmorillonite were selected for the determination of the adsorption kinetics and isotherms. On all the tested materials adsorption took place within one hour contact with fumonisins solutions. Adsorption isotherms have pointed out that the modified clays exhibited a higher adsorptive capacity than the unmodified clay. It was also demonstrated that, notwithstanding the reduced structural difference between FB 1 and FB 2 , they were differently adsorbed on the modified clays. Addition of 2 % modified clays to contaminated maize allowed a reduction of more than 70% and 60% of the amount of FB 1 and FB 2 released in solution. Although in vivo experiments are required to confirm the effectiveness of the organically modified clays, these preliminary results suggest that these materials are promising as fumonisins binders.
