چکیده
|
Based on the inhibitory effect of uric acid (ua) on luminol-co2+ chemiluminescence (cl) system,a sensitive method for the determination of ua at nanomolar level by flow injection (fi) cl was proposed. the proposed method was successfully applied to real-time monitoring of ua excretion in human 24 h urine with different food intake,showing that meats,vegetables,and porridge intake caused differential ua excretions of 879,798,and 742 mg,respectively. it was also found that ua concentrations in urine under the three kinds of food intake simultaneously reached maximum at 2 h after meals with the values of 417,318,and 288 g ml-1,respectively. the ua concentration in human serum was also determined by this approach,and the possible mechanism of luminol-co2+-ua cl reaction was discussed in detail. © 2013 jiajia wang et al.
