The adsorption and desorption behavior of tetracycline on an Alfisol and an Ultisol was investigated at varying soil/solution ratios (1:10, 1:50, and 1:100) and different cation types (CaCl 2 , KCl, and NaCl) and H 2 O using a batch equilibration experiment. Kinetic studies revealed that the adsorption of tetracycline on the two soils was rate limited, and the adsorption kinetics could be well described by the Elovich equation and exponent equation. Changes in the soil/solution ratio affected…

Effects of Soil-to-Solution Ratio on Sorption-Desorption Isotherms of Zinc in a Sandy Soil

Sorption reaction depends on various factors, including number of available sorption sites, total amount of sorptive material in solution and probability of effective contact between sorption sites

Competitive adsorption and desorption of oxytetracycline and cadmium with different input loadings on cinnamon soil

PurposeThe binary competitive effect could obviously influence the fate and transport behavior of oxytetracycline (OTC) and cadmium (Cd2+) in cinnamon soil. However, two pollutants loading into soil

Adsorption of Tetracycline from Aqueous Solution by Aerobic Granular Sludge-based Biochar: Affecting Factors, Kinetics, Isotherms, and Mechanisms

In this experiment, the influencing factors of tetracycline (TC) removal by adsorption with the aerobic granular sludge-based biochar (BC) were analyzed. In particular, the specific surface area,

The Presence of Cu Facilitates Adsorption of Tetracycline (TC) onto Water Hyacinth Roots

The interaction between Cu(II) and TC under different environmental conditions should be taken into account to understand the environmental behavior, fate, and ecotoxicity of TC.

Results show that no general rules can be proposed to describe univocally the relation between the shape of isotherms and the nature of adsorbate-adsorbent system, and there is a strong need for experimental results.

Sorption of three tetracyclines by several soils: assessing the role of pH and cation exchange.

A sorption model in which species-specific sorption coefficients normalized to pH-dependent CEC fit the data well across all soils except for a soil rich in gibbsite and high in AEC, which described most of the sorption observed as a function of pH for eight soils that varied in their mineralogy and pH (pH ranged from 4 to 8).

Estimation of soil sorption coefficients of veterinary pharmaceuticals from soil properties

Environmental exposure assessment of veterinary pharmaceuticals requires estimating the sorption to soil. Soil sorption coefficients of three common, ionizable, antimicrobial agents (oxytetracycline

Complexation of the antibiotic tetracycline with humic acid.

Interaction of tetracycline with aluminum and iron hydrous oxides.

Spectroscopic evidence indicates that tricarbonylamide and carbonyl functional groups of tetracycline could be responsible for sorption to mineral surfaces, which will increase understanding of the environmental occurrence, fate, and transport characteristics of antibiotics, which are considered as emerging organic contaminants.

Investigating the molecular interactions of oxytetracycline in clay and organic matter: insights on factors affecting its mobility in soil.

Several mechanisms of interaction of oxytetracycline in clay are proposed based on the adsorption isotherms and the results from X-ray diffraction (XRD) and Fourier transform-infrared (FT-IR) analyses.

Sorption of tetracycline and chlortetracycline on K- and Ca-saturated soil clays, humic substances, and clay-humic complexes.

The results indicate that tetracyclines are dominantly sorbed on soil clays and that HS in clay-HC either mask sorption sites on clay surfaces or inhibit interlayer diffusion of tetrACYclines.
