摘要
在高原自然光条件下利用纳米Cu2+/Ti O2复合光催化剂对高原制药废水中阿莫西林进行了光催化降解实验,研究了不同温度煅烧及催化剂中不同Cu2+浓度对水体中阿莫西林降解率的影响。结果表明:在自然光下照射下,催化剂用量为1 g/L,掺入1.0%Cu2+、煅烧温度为700℃的Cu2+/Ti O2纳米催化剂8 h后对水体中阿莫西林的降解率最高达到75%。纳米Cu2+/Ti O2复合光催化剂对制药废水中阿莫西林的降解有一定的效果。
We investigated the photodegradation rate of amoxicillin in water sample exposed to sunlight by using the Cu^2 ＋/ Ti O2 nanometer photo catalyst which was made by ourselves. The effect of different calcination temperature combined with a series of Cu^2 ＋concentration on the degradation rate of amoxicillin in water was investigated. Results showed that under the natural light condition,with the addition of 1g / L Cu^2 ＋/ Ti O2 nanometer photocatalyst（ prepared at 700 ℃ calcination temperature,Cu^2 ＋accounts for 1. 0%）,the amoxicillin degradation rate reached as high as 75% after 8hours.
