Abstract

In this study, removal of Tetracycline (TC) antibiotics from artificially contaminated water has been investigated with the aim of detoxifying pharmaceutical wastewater before their safe disposal onto land or into river waters. The adsorption of TC occurred by studying the effects of adsorbent dose, TC concentration and contact time at fixed temperature= 25ºC and PH=7. The removal of TC effluent is a rapid process. At adsorbent dose 2 g/L and at room temperature, the adsorption equilibrium is reached after 60 min for low concentration and 90 min for high antibiotic concentration and kinetics follow a pseudo-second-order model. The adsorption isotherm is in good agreement with the Langmuir model. The adsorption of TC on the surface of LM biomass was done in monolayer and maximum adsorption capacity of TC was determined as 18.26 mg/g. Also in this study, have also been done five types of error functions. The results of error functions showed that the best fit was obtained for the Langmuir isotherm and pseudo-second-order model with  =0.9975 and  = 0.9912.
