Abstract:

A sensitive method for determining uric acid (UA) at nanogram level by flow injection (FI) chemiluminescence (CL) was described, based on the inhibitory effect of UA on luminol-KIO4 CL system. It was found that the CL intensity decrements were linearly proportional to the logarithm of UA concentrations ranging from 3.0 to 500.0 ng mL−1 with the detection limit of 1.0 ng mL−1 (3σ). At a flow rate of 2.0 mL min−1, the whole determining performance including sampling and washing could be accomplished in 36.0 s, offering the sample efficiency of 100 h−1. The proposed method was successfully applied to in vitro monitoring of UA excretion in human 24 h urine with different diets, with results showing that porridge, vegetables and meats intake caused differential UA excretions of 722, 767 and 854 mg, respectively
