Abstract :

A system involving sugarcane bagasse (SCB) was developed to remove tetracycline (TC) from water. This system, composed of glass columns and peristaltic pump, was optimized and, for pH and flow rate, the best values were 7.0 and 25 mL min^-1 respectively. After optimization, adsorption isotherm was built and it was possible to calculate maximum adsorption capacity of SCB for TC (MAC_SCB-TC = 0.31 mg g^-1). Additionally, real samples of pretreated water, from Espírito Santo Sanitation Company, were enriched with TC at 0.1 mg mL^-1 and passed through glass columns paked with SCB or activated carbon (AC) to compare the performance of SCB. The adsorption capacity of TC demonstrated by SCB (98%) was higher than AC (72%). The results encourage more advanced studies of technical and economic applicability of SCB in water treatment.
