%X 利用高温煅烧的方法合成了纳米TiO<sub>2</sub>，使用响应面法研究其在不同条件下光催化降解刚果红的活性。通过单因素实验来研究其中的主要影响因素，利用响应面法对主要影响因素进行分析和优化，得到最佳期望值。通过实验数据分析，构建了二次多项式函数模型。预测最佳反应条件为：CR的初始浓度为17.954 mg/L，TiO<sub>2</sub>的加入量8.219 mg，光照时间139 min，CR的降解率为86.93%。<br />
Nano-TiO<sub>2</sub> was synthesized by calcination at high temperature and its photocatalytic degradation activity of Congo red was studied by response surface method under different conditions. The main influencing factors were studied by single factor experiment, and the response surface method was used to analyze and optimize the main influencing factors, and the best-expected value was obtained. Through the analysis of experimental data, a quadratic polynomial function model was constructed. The optimal reaction conditions were as follows: the initial concentration of CR was 17.954 mg/L, the additional amount of TiO<sub>2</sub> was 8.219 mg, the illumination time was 139 min, and the degradation rate of CR was 86.93%.
