dc.description.abstract	The extracellular polymeric substrate (EPS) extracted from Klebsiella sp.

Adsorption efficiency was evaluated at different conditions. Results showed that optimal adsorption efficiency was 71.68 % with 60 mg L-1 of EPS from strain J1 and 90 μL of 10 % (w/v) CaCl2 in 100 mL of tetracycline solution (80 μg L-1) with pH of 8.0. Experimental data was fitted well with Langmuir, Freundlich isotherm, and pseudo-second-order models.

Thermodynamic analysis indicated that adsorptive reaction was exothermic from 20 to 40 °C. In addition, humic acid (HA) showed little effect on the tetracycline adsorption by MFX.

Abstract:

The extracellular polymeric substrate (EPS) extracted from Klebsiella sp. J1 was used to adsorb low concentrations of tetracycline, and the efficiency and mechanism of tetracycline adsorption by EPS from strain J1 were studied. Adsorption efficiency was evaluated at different conditions. Results showed that optimal adsorption efficiency was 71.68 % with 60 mg L-1 of EPS from strain J1 and 90 μL of 10 % (w/v) CaCl2 in 100 mL of tetracycline solution (80 μg L-1) with pH of 8.0. Experimental data was fitted well with Langmuir, Freundlich isotherm, and pseudo-second-order models. Analyses of E value, Ea value, thermodynamics, zeta potential variation, and Fourier transform infrared spectroscopy (FTIR) spectra proved that chemisorption was the main adsorption type and bridging was the main adsorption mechanism. Thermodynamic analysis indicated that adsorptive reaction was exothermic from 20 to 40 °C. In addition, humic acid (HA) showed little effect on the tetracycline adsorption by MFX.
