Resumo: | Brazil is well known as the worldwide production of animal protein and there for the highest consumer of the antibiotic enrofloxacin, the most common the second generation antibiotics used in veterinary medicine. The wastewater treatment with TiO2/solar photodecomposition natural, low-cost energy integrated with the renewable biocarbon absorbent. Such integrated process rises a possible tool to control and reduce the enrofloxacin environmental impact on soil and surface water quality loss. The process starts with the TiO2 addition on different initial enrofloxacin concentrations, after the suspension 120 min of the stirring time inside the solar chamber the collected suspension aliquots (20 minutes each) and the addition to micronized biocarbon present in the falcon tubes. The falcon tubes are further centrifugated and the supernatant measured using spectrophotometric analysis. The maximum removal percentage was 74.63 % with higher correspondence with the kinetics of pseudo-second-order and Langmuir isotherm with RL in the range of 0 to 1and the surface coverage percentage of 92 % in the higher concentrated system. |

Brazil is well known as the worldwide production of animal protein and there for the highest consumer of the antibiotic enrofloxacin, the most common the second generation antibiotics used in veterinary medicine. The wastewater treatment with TiO2/solar photodecomposition natural, low-cost energy integrated with the renewable biocarbon absorbent. Such integrated process rises a possible tool to control and reduce the enrofloxacin environmental impact on soil and surface water quality loss. The process starts with the TiO2 addition on different initial enrofloxacin concentrations, after the suspension 120 min of the stirring time inside the solar chamber the collected suspension aliquots (20 minutes each) and the addition to micronized biocarbon present in the falcon tubes. The falcon tubes are further centrifugated and the supernatant measured using spectrophotometric analysis. The maximum removal percentage was 74.63 % with higher correspondence with the kinetics of pseudo-second-order and Langmuir isotherm with RL in the range of 0 to 1and the surface coverage percentage of 92 % in the higher concentrated system. |
