摘  要:
利用Co2+催化过氧化苯甲酰(BPO)与鲁米诺的发光反应,建立了静态注射化学发光检测面粉中BPO的方法。单样检测周期为1 h,检测限为3×10-9g/mL,线性范围1.0×10-8~1.0×10-6g/mL,加标回收率为93.4%~101.7%,对浓度为5.0×10-8g/mL的BPO进行测定,RSD=2.29%(n=11)。该方法应用于测定面粉中的BPO效果良好。

摘  要:
A new method for determination of benzoyl peroxide(BPO) by static injection chemiluminescence has been developed.The time of measuring a sample was 1 hour.The detection limit was 3×10-9 g/mL.The rate of recovery was between 93.4% and 101.7%.The linear range was from 1.0×10-8 g/mL to 1.0×10-7 g/mL.The relative standard deviation(n=11) was 2.29% for 5.0×10-8 g/mL BPO.Results indicated that this method could be used in the determination of BPO in flour.
