Abstract
ABSTRACT The validity of the mathematical model to extract the antibiotics contaminants such as tetracycline (TC) and ciprofloxacin (CIP) through emulsion and Pickering emulsion liquid membrane (ELM and PELM) was studied in this research. In this work, heptane was used as a diluent, TBP as carrier, HCl as the internal phase, and Span80 or Fe 2 O 3 modified with oleic acid as a stabilizing agent. The used mathematical model is already available, but it has not yet been tested for the extraction of any antibiotics before. The model results show a very good matching when compared with the obtained experimental data through various process parameters, including homogenizer speed, surfactant or nanoparticles concentration and carrier concentration. The error percentage was less than 2% for TC and CIP by using ELM process and about 1% for both TC and CIP by using PELM process.
