The sorption interaction of three widely used tetracycline antibiotics, namely, tetracycline, chlortetracycline, and oxytetracycline, under various conditions time, pH, temperature, ionic strength, exchangeable cations on illites kaolinites was examined. First-order reaction indicated diffusion-controlled adsorption, maximum adsorption occurring at pH values 3.5, 3, 4 for respectively. Adsorption isotherms “L” type showed that the antibiotics in order chlortetracycline > oxytetracycline...

Abstract Adsorption of oxamyl and phosphamidon (Dimecron) was determined from dilute solutions montmorillonite saturated with different cations, e.g., Li + , Na K Cs Fe 3+ Al . found to be greater than adsorption Dimecron. The shapes the isotherms depended on exchangeable cations. varied directly polarizing power cation inversely changes in temperature, organic matter, ionic strength up 0.6, after which it became constant. enthalpy (Δ H °) calculated temperature coefficient equilibrium...
The presence of tetracyclines in soil and surface water is an emerging concern. present study was undertaken to investigate remediation tetracylines (tetracycline (TC), oxytetracycline (OTC) chlortetracycline (CTC)) from aqueous solution using vetiver grass, lettuce, sunflower root exudates by tomato, Indian mustard carrot plant. data this denote that remedy water. % after 63 days treatment 87-61 for TC; 88-68 OTC 87-68 CTC. at lower concentration antibiotics lettuce more than 99% faster or...
Aims: To study the effect of various doses tetracycline (TC), oxytetracycline (OTC) and chlortetracycline (CTC) on enzymatic (DHA, acid phosphatase, alkaline urease catalase) activity in sewage amended un-amended alluvial soil. Methodology: A laboratory incubation was conducted during 2012-2013 an Aligarh farm The studied presence three antibiotics soil; soil with sludge; mixture sludge tetracyclines at different time intervals [(0 (4h), 7, 14, 21, 35, 56, 70,91d]. Results: Activity all...
Summary Exchange equilibria involving nickel ions on potassium and calcium kaolinites were studied using exchange isotherms derived thermodynamic parameters. The equilibrium was attained within 3 h maximum adsorption occurred at pH 5.5. 5.5 an time of yielded isotherms, constants standard fne energy values indicating a higher preference for the kaolinite surface. A stronger binding surface suggested by enthalpy changes entropy indicate increase in order system which may be due to hydration...
