Abstract

Using the response surface method (RSM), the temperature, time and nickel-iron ratio of the synthesis of NiFe-LDH photocatalyst were used as influencing factors, the removal rate of norfloxacin (NOR) was the response factor, the Sub-mathematical equation was structured. The optimized model predicts that the optimal synthesis temperature, time and nickel-iron ratio are: 127.1 °C, 36 min, 2.854:1, and the removal rate of NOR is 88.25%. The actual removal rate of NOR over NiFe-LDH prepared under the conditions was 89.14%, indicating that the model was successfully established. It provides a reference for the synthesis of hydrotalcite by microwave method.

摘要

采用响应面法（RSM），以合成NiFe-LDH光催化剂的温度、时间和镍铁比为影响因素，以诺氟沙星（NOR）的去除率为响应因素，亚数学方程是结构化的。优化模型预测最佳合成温度、时间和镍铁比为：127.1 ℃，36 min，2.854:1，NOR的去除率为88.25%。在该条件下制备的NiFe-LDH上NOR的实际去除率为89.14%，表明模型建立成功。为微波法合成水滑石提供参考。
