“…These values were of about the same magnitude as the initial rate of 0.32 mmol/g-h, the rate constant of 6.4 g/mmol-h, and the equilibrium adsorption value of 0.22 mmol/g for CIP adsorption on the same mineral (Jiang et al 2013). However, the initial rate was much lower than 1.3 and 3.8 mmol/g-h, and the equilibrium adsorption value was also lower than 0.44 mmol/g for TC adsorption on swelling clay minerals Na-and Ca-montmorillonite (Li et al 2010a). …”

Birnessite is one of the most common manganese oxides in the clay-sized fraction (\2 lm) of soils and has high cation exchange capacity and larger surface area. Birnessite was previously studied for decomposition of selected antibiotics from water. In this study, the removal of tetracycline (TC) by birnessite from aqueous solution was investigated as a function of initial tetracycline concentration, solution pH, temperature, and equilibrium time. Changes in solid phase after TC adsorption and desorption were characterized by X-ray photoelectron spectroscopy, X-ray diffraction (XRD), and Fourier transform infrared analyses. Desorption of exchangeable cations accompanying TC removal and partial desorption of TC from birnessite by AlCl 3 confirmed that cation exchange was responsible for TC removal at low initial concentrations. Both the external and internal surface areas were readily available for TC uptake by birnessite. The intercalated TC formed a horizontal monolayer configuration in the interlayer of birnessite as deduced from XRD analyses.

“…In this study, the intercalation of TC into the birnessite interlayer could only be achieved partially, which may account for the much lower TC uptake in comparison with the CEC of the mineral. In contrast, intercalation of TC into swelling clay mineral montmorillonite resulted in d-spacing expansion to 22 Å (Li et al 2010a).…”

“…Normally the adsorption of tetracycline onto clays exhibits Langmuir type isotherms (Li et al 2010;Sithole and Guy 1987a) or Freundlich type (Kulshrestha et al 2004) and greatly influenced by pH and ionic strength, e.g. decreased as the ionic strength and pH increased (Figueroa et al 2004;Kulshrestha et al 2004;Li et al 2010;Sithole and Guy 1987a;Wang et al 2010). The adsorption normally involved two types of mechanisms depending on pH condition.…”

Tetracycline adsorption on kaolinite: pH, metal cations and humic acid effects

et al. 2011

Contamination of environmental matrixes by human and animal wastes containing antibiotics is a growing health concern. Because tetracycline is one of the most widely-used antibiotics in the world, it is important to understand the factors that influence its mobility in soils. This study investigated the effects of pH, background electrolyte cations (Li(+), Na(+), K(+), Ca(2+) and Mg(2+)), heavy metal Cu(2+) and humic acid (HA) on tetracycline adsorption onto kaolinite. Results showed that tetracycline was greatly adsorbed by kaolinite over pH 3-6, then decreased with the increase of pH, indicating that tetracycline adsorption mainly through ion exchange of cations species and complexation of zwitterions species. In the presence of five types of cations (Li(+), Na(+), K(+), Ca(2+) and Mg(2+)), tetracycline adsorption decreased in accordance with the increasing of atomic radius and valence of metal cations, which suggested that outer-sphere complexes formed between tetracycline and kaolinite, and the existence of competitor ions lead to the decreasing adsorption. The presence of Cu(2+) greatly enhanced the adsorption probably by acting as a bridge ion between tetracycline species and the edge sites of kaolinite. HA also showed a major effect on the adsorption: at pH < 6, the presence of HA increased the adsorption, while the addition of HA showed little effect on tetracycline adsorption at higher pH. The soil environmental conditions, like pH, metal cations and soil organic matter, strongly influence the adsorption behavior of tetracycline onto kaolinite and need to be considered when assessing the environmental toxicity of tetracycline.

“…Additionally, electrostatic attractive/repulsive forces between metal ions coordinated to O-/Nfunctionalities of functionalized MWCNTs and zwitterionic tetracycline molecules are also expected to occur (Ji et al, 2010b;Li et al, 2010;Zhao et al, 2011). Note that when normalizing the adsorption affinities with BET surface area, both in the absence and presence of Cu(II), OH-MWCNTs and COOHMWCNTs can accumulate more tetracycline than NH 2 -MWCNTs (Fig.…”

“…Tetracycline is a commonly used antibiotic in livestock production for disease treatment and growth promotion (Halling-Sørensen et al, 1998;Hirsch et al, 1999;Luo et al, 2011), and the amphoteric molecule has multiple ionizable groups/moieties (e.g., phenol, amino, and enone) which are capable of polar interactions at environmentally relevant pH values (Ji et al, 2010a;2010b;Li et al, 2010;Sun et al, 2010;Zhang et al, 2011;Zhao et al, 2011;Gao et al, 2012). Functionalized MWCNTs, including hydroxylated MWCNTs (OH-MWCNTs), carboxylated MWCNTs (COOHMWCNTs), and aminated MWCNTs (NH 2 -MWCNTs), were used, and graphitized MWCNTs (G-MWCNTs) were included as additional adsorbents for assessing the roles of the graphene structure in adsorption.…”

Abstract:The environmental applications and implications of functionalized carbon nanotubes (CNTs) have received much attention. In this study, the adsorption interactions of graphitized multi-walled carbon nanotubes (G-MWCNTs) and functionalized MWCNTs, including hydroxylated MWCNTs (OH-MWCNTs), carboxylated MWCNTs (COOH-MWCNTs), and aminated MWCNTs (NH 2 -MWCNTs), for tetracycline in the aqueous solution were systemically investigated, and the effects of Cu(II) and Ni(II) (two metal ions commonly present in aquatic environments) on MWCNTs-tetracycline interactions were examined. Results showed that the adsorption affinities followed an order of G-MWCNTs>OH-MWCNTs>COOH-MWCNTs>NH 2 -MWCNTs, indicating that the adsorptive interactions between MWCNTs and tetracycline can be largely affected by the types and abundance of functionalities on the MWCNTs surfaces. Both Cu(II) and Ni(II) had a negligible effect on the adsorption of tetracycline to G-MWCNTs, but varied effects of the metal ions were observed for the three functionalized MWCNTs. In general, Cu(II) exhibited a more pronounced effect for the adsorption of tetracycline than Ni(II), due to the degree of complexing capability.
