以牡蛎壳为载体,采用超声浸渍法-焙烧制备牡蛎壳负载铜的催化剂,利用电镜扫描(SEM)、 X射线衍射(XRD)对催化剂进行表征。以酸性红FRL为降解目标物,研究此催化剂催化过硫酸钠降解酸性红FRL的性能。考察了催化剂焙烧的条件、氧化剂浓度、催化剂用量和初始染料浓度对降解的影响。结果表明,催化剂经500℃焙烧3 h,催化活性较高；当初始污染物浓度为120 mg·L-1,氧化剂浓度为0.28 g·L-1,催化剂用量为0.70 g·L-1时,降解2.5 h,酸性红FRL染料溶液的降解率可达80.3%以上。

The copper-loaded oyster shells as catalysts were prepared through ultrasonic impregnation-calcination and were characterized by scanning electron microscope ( SEM) and X-ray powder diffraction ( XRD). The degradation performance by persulfate was investigated through the catalyst with acid red FRL as targeted pollutant. The effects of the factors, such as calcination conditions, concentration of oxidant, dosage of catalyst and initial concentration of pollutants were studied. The results showed that catalyst could have good activity after being heated for 3 h at 500 ℃. The removal rate of acid red FRL could reach 80.3% after 2.5 h under certain conditions: initial concentration of acid red FRL of 120 mg·L-1 , concentration of oxidizing agent of 0.28 g·L-1 , catalyst dosage of 0.70 g·L-1 .
