【摘要】：利用黃綠青霉素對魯米諾-過氧化氫-納米氧化銅化學(xué)發(fā)光體系的抑制作用檢測飲用水中可能出現(xiàn)的突發(fā)性污染,并對測定體系的條件進(jìn)行單因素試驗和響應(yīng)面試驗優(yōu)化。結(jié)果表明:在優(yōu)化的實驗條件下,黃綠青霉素檢測線性范圍為0.005~3 mg/L,檢出限為8.2×10~(-5) mg/L。對質(zhì)量濃度為0.005 mg/L的黃綠青霉素進(jìn)行平行測定11次,相對標(biāo)準(zhǔn)偏差為2.3%,黃綠青霉素加標(biāo)回收率范圍為78%~91%。該方法簡便快捷、實用性強,可應(yīng)用于飲用水中黃綠青霉素突發(fā)性污染在線快速檢測。
[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.
