Remoção de ampicilina sódica da água por meio da técnica de adsorção utilizando carvões ativados

Abstract

Drugs are the active principles that originate drugs for a specific therapeutic purpose. Among these, antibiotics deserve to be highlighted due to their high consumption, since after being consumed and metabolized by humans, they are mostly excreted and transported to sewage treatment plants (ETEs). The present work aimed to delimit the use of antibiotics in the state of Tocantins and in Palmas-TO and to evaluate the removal of the antibiotic ampicillin sodium from the water, in a batch regime, using dosages of 5.00 mg/L, 27.50 mg/L and 50 .00 mg/L of powdered activated carbon (PAC), one produced from the epicarp of the Babaçu Coconut and the other made from steam-activated wood, in contact times of 5.00 min, 32.50 min and 60, 00 min.. The study water (ultrapure) was prepared with a concentration of 50.00 mg/L of sodium ampicillin, and residual concentration readings were performed by high performance liquid chromatography (HPLC). The study resulted in two articles, one review and the other bench test, where the first delimited that ampicillin is among the thirty most consumed antibiotics in Tocantins and Palmas-TO and the second found an efficiency of ampicillin sodium removal in 48.73% synthetic water with 27.50 mg/L of Coconut Babaçu CAP in 32.50 min. While the wood PAC was not efficient under the charcoal dosages and contact time analyzed.
