Determination of Levodroproizine by Flow Injection Chemiluminescence Method

A new chemiluminescence method combined with flow injection technique was developed for the determination of levodroproizine,which is based on the CL reaction of levodroproizine and potassium permanganate with formaldehyde as an enhancement reagent.The linear range for levodroproizine was is 0.01-4 μg/mL with detection limit of 0.94 ng/mL.The the relative standard deviation was 1.06%(n=11) for 1×10~(-6) g/mL levodroproizine.The synthetic samples were analyzed by the proposed method for levodroproizine determination with satisfactory results.
