“…Application of animal manure containing non-degraded antibiotics may result in retention of antibiotics on the surface and in the interlayer of montmorillonite. Previous results showed that TC intercalated into the interlayer of swelling clays was thermally more stable than its crystalline counterpart (Chang et al 2009). A similar observation was found for CIP intercalation into swelling clays (Jiang et al 2013).…”

As the uptake of cationic drugs, such as tetracycline (TC), was attributed to cation exchange, the stability of adsorbed TC on a Ca-montmorillonite SAz-2 was studied using cationic solutions of different valence charges under different pH conditions. At the initial loading of 356 mg g -1 , the amounts of TC desorbed by 0.05 M AlCl 3 , CaCl 2 , and NaCl were 133 ± 4, 83 ± 6, and 50 ± 4 mg g -1 , respectively, or 37, 23, and 14 %. However, when the amount or percentage of TC desorbed was normalized to the equivalence of each cation, the values were in the range of 44-50 mg g -1 or 11-14 % per 10 mmol of charge. The kinetics of TC desorption were moderately fast and almost reached equilibrium in 6 h. The results followed the pseudo-second-order kinetic model with reaction rate in the order of AlCl 3 [ CaCl 2 [ NaCl at a higher initial TC loading level. The total amount of TC desorbed after five desorption cycles followed the order of AlCl 3 [ CaCl 2 [ NaCl, too, suggesting that cations with higher positive charges, thus, less hydrated, are preferred to remove adsorbed cationic drugs. The FTIR analyses showed larger band shift when Al 3? was used as the desorbing reagent. The XRD patterns before and after TC desorption revealed no changes in basal spacing, even after five desorption cycles, suggesting that the removal of TC from SAz-2 was largely from the external surfaces.

“…intercalation vs external sorption), the influence of exchange cations on adsorption, participation of the carboxylate, ketone, and protonated N in the piperazinyl group in adsorption as a function of pH, and the influence of coadsorbing cations Nowara et al, 1997;Pei et al, 2010;Wang et al, 2011;Wu et al, 2010;Yan et al, 2012). Similar types of FTIR studies focused on tetracycline class antibiotic adsorption have proved useful in evaluating the mechanisms and the types of complexes formed between tetracyclines and minerals (Chang et al, 2009a(Chang et al, , 2009bGu and Karthikeyan, 2005a;Kulshrestha et al, 2004;Zhao et al, 2012b).…”

“…As shown in Table 1, the sorption capacities of soil clays for TCs were about 32-460 mg/g. Montmorillonite had much higher affinity for TCs than others, likely due to the intercalation of TCs into the interlayers of clays (Chang et al 2009a). Parolo et al (2008) examined the adsorption of TC on a Patagonia montmorillonite and observed that the basal spacing of the clay mineral increased from 12.6 to 19.5 Å in the presence of TCs.…”

“…Characteristics of both clays and PCs may be modified during the adsorption interaction. Colloids may protect PCs from degradation (Chang et al 2009a;Jiang et al 2013b) and the biocolloids (e.g., bacteria and viruses) can be domesticated by PCs (Sengeløv et al 2003;Lv et al 2013). After adsorption, some PCs have high affinities with soil matrix which are thought to be immovable may move together with the colloids they bind (Fig.…”

“…Tetracyclines (TCs) are a group of natural and semisynthetic antibiotics, which are widely used in human beings and animals for inhibiting the synthesis of bacterial proteins towards a variety of microorganisms (Chopra and Roberts 2001). The interactions between many TCs and clay minerals have been investigated (Figueroa et al 2004;Aguzzi et al 2005;Parolo et al 2008;Chang et al 2009a;Aristilde et al 2010;Avisar et al 2010;Zhao et al 2012).

What happens when pharmaceuticals meet colloids

Pharmaceuticals (PCs) have been widely detected in natural environment due to agricultural application of reclaimed water, sludge and animal wastes. Their potential risks to various ecosystems and even to human health have caused great concern; however, little was known about their environmental behaviors. Colloids (such as clays, metal oxides, and particulate organics) are kind of substances that are active and widespread in the environment. When PCs meet colloids, their interaction may influence the fate, transport, and toxicity of PCs. This review summarizes the progress of studies on the role of colloids in mediating the environmental behaviors of PCs. Synthesized results showed that colloids can adsorb PCs mainly through ion exchange, complexation and non-electrostatic interactions. During this process the structure of colloids and the stability of PCs may be changed. The adsorbed PCs may have higher risks to induce antibiotic resistance; besides, their transport may also be altered considering they have great chance to move with colloids. Solution conditions (such as pH, ionic strength, and cations) could influence these interactions between PCs and colloids, as they can change the forms of PCs and alter the primary forces between PCs and colloids in the solution. It could be concluded that PCs in natural soils could bind with colloids and then co-transport during the processes of irrigation, leaching, and erosion. Therefore, colloid-PC interactions need to be understood for risk assessment of PCs and the best management practices of various ecosystems (such as agricultural and wetland systems).
