A new chemiluminescence method for determination of clonazepam and diazepam based on 1-Ethyl-3-Methylimidazolium Ethylsulfate/copper as catalyst

- The ionic liquid 1-Ethyl-3-Methylimidazolium Ethylsulfate catalyzed Benzodiazepines direct chemiluminescence.
- The Benzodiazepines-H2O2-1-Ethyl-3-Methylimidazolium Ethylsulfate CL system is very selective in determination of the drugs.
- Benzodiazepines in pharmaceutical drugs are determined with high accuracy and precision.
- The detection limits (LOD) of Benzodiazepines is obtained less than 30 ng/ml.
- The common ions cannot interfere to the detection of Benzodiazepines.
