Resumo: | The study presents the antibiotics TiO2/solar photodecomposition followed by adsorption using micronized biocarbon. The cephalexin and amoxicillin antibiotics are very popular in Brazil and possibly the mostly found in medical prescriptions. The adsorption process using biocarbon reduce the presence of photodecomposition byproducts. The experimental project was planned to optimize the efficiency of the integrated processes (photodecomposition and adsorption) to remove the antibiotics mixture from the polluted water. The first study was only one antibiotic at the time, the amoxicillin followed by cephalexin after that was studied the binary system. The maximum single amoxicillin removal percentage was 94.74 %, the single cephalexin was 69.45%, and for the binary system the higher removal percentage after solar/TiO2 photodecomposition and biocarbon adsorption was 59.95% correspondent with 8.84% of cephalexin and 91.16% of amoxicillin. The cephalexin addition to the binary system reduces the total removal percentage. The integrated processes indicate better correspondence with the pseudo-second-order kinetics K2, and Langmuir, Freundlich, and Radlich-Peterson isotherms to amoxicillin and cephalexin experiments and the binary system. |

The study presents the antibiotics TiO2/solar photodecomposition followed by adsorption using micronized biocarbon. The cephalexin and amoxicillin antibiotics are very popular in Brazil and possibly the mostly found in medical prescriptions. The adsorption process using biocarbon reduce the presence of photodecomposition byproducts. The experimental project was planned to optimize the efficiency of the integrated processes (photodecomposition and adsorption) to remove the antibiotics mixture from the polluted water. The first study was only one antibiotic at the time, the amoxicillin followed by cephalexin after that was studied the binary system. The maximum single amoxicillin removal percentage was 94.74 %, the single cephalexin was 69.45%, and for the binary system the higher removal percentage after solar/TiO2 photodecomposition and biocarbon adsorption was 59.95% correspondent with 8.84% of cephalexin and 91.16% of amoxicillin. The cephalexin addition to the binary system reduces the total removal percentage. The integrated processes indicate better correspondence with the pseudo-second-order kinetics K2, and Langmuir, Freundlich, and Radlich-Peterson isotherms to amoxicillin and cephalexin experiments and the binary system. |
