摘要：

The removal of tetracycline (TC) using a TiO2/Ge composite under UV-A irradiation was examined. Response surface methodology based on a mixture analysis experiment was applied to determine the optimal molar ratio of the TiO2/Ge composite (69:31). The photocatalytic degradation test of TC over the optimal TiO2/Ge composite showed around 95% removal efficiency based on CODCr during the 240 min UV-A irradiation. In addition, a toxicity during the photocatalysis of TC was evaluated. The results obtained indicated that the system proposed in this study is very efficient for the mineralization of TC.
