摘要
以阳离子染料番红花红为降解对象,广枣多糖镧作为催化剂,氢氧化铝作为负载体对广枣多糖镧降解有机污染物进行探索研究。按1:7、1:10、1:13、1:15的比例将广枣多糖镧负载在氢氧化铝上,在光照的条件下利用分光光度计测降解后的番红花红吸光度,计算番红花红的降解率。利用标准曲线得线性回归方程为y=338.17 x-0.0184,相关系数r=0.9997。实验结果表明,广枣多糖镧与氢氧化铝比例为1:13时番红花红的降解效果最好。
The experiment was to explore the degradation of organic pollutants in polysaccharides byspectrophotometry.Absorbance,calculate the degradation rate of saffron.The linear regression equation was y=338.17x-0.0184 and the correlation coefficient r is 0.9997.The experimental of jujube polysaccharides.The cationic dyes were used as the catalyst and the aluminum hydroxide as the carrier.The ratio of polysaccharide to aluminum hydroxide was 1:7、1:10、1:13、1:15 and the ratio of polysaccharide to aluminum hydroxide was measured results showed that the degradation efficiency of polysaccharide lanthanum and aluminum hydroxide was 1:13.
