ABSTRACT

Simple and low cost method for extraction of Cetirizine hydrochloride and Cyclopentolate Hydrochloride by polyurethane foam from aqueous systems. PUF was characterized using FT-IR and scanning electron microscopy. The batch technique was performing to evaluate the effects of initial pH, contact time, volume of sample and initial concentration of both drugs. The isotherm for absorption process was studied. It is found that the Cetirizine Hydrochloride in undergo Freundlich isotherm (R2=0.9743) but in Cyclopentolate Hydrochloride undergo Langmuir isotherm (R2 =0.9809).

Keywords :polyurethane foam (PUF); Cetirizine hydrochloride; Cyclopentolate Hydrochloride; separation; adsorption isotherms.
