【摘要】：利用黄绿青霉素对鲁米诺-过氧化氢-纳米氧化铜化学发光体系的抑制作用检测饮用水中可能出现的突发性污染,并对测定体系的条件进行单因素试验和响应面试验优化。结果表明:在优化的实验条件下,黄绿青霉素检测线性范围为0.005~3 mg/L,检出限为8.2×10~(-5) mg/L。对质量浓度为0.005 mg/L的黄绿青霉素进行平行测定11次,相对标准偏差为2.3%,黄绿青霉素加标回收率范围为78%~91%。该方法简便快捷、实用性强,可应用于饮用水中黄绿青霉素突发性污染在线快速检测。
[Abstract]:The inhibition of yellow-green penicillin on luminol hydrogen peroxide nano copper oxide chemiluminescence system was used to detect the sudden pollution in drinking water and the conditions of the determination system were optimized by single factor test and response surface test. The results showed that under the optimized experimental conditions, the detection limit of xanthocyanin was 8.2 脳 10 ~ (-5) mg/L. in a linear range of 0.005 ~ (-3) mg/L,. Eleven times of parallel determination of yellow green penicillin with a mass concentration of 0.005 mg/L were carried out, and the relative standard deviation was 2.3. The recovery rate of yellow green penicillin was 780.91%. The method is simple, rapid and practical, and can be applied to the on-line rapid detection of the sudden pollution of xanthocyanin in drinking water.
