DETERMINATION OF THIOUREA BY FLOW INJECTION WITH CHEMILUMINESCENCE
A new method of flow injection hyphenated with chemiluminescence for determining thiourea is developed.The method is based on that thiourea reduces Fe(Ⅲ) to Fe(Ⅱ) and the reaction is coupled with the chemiluminescence system lumino-O2-Fe(Ⅱ).Detection limit of the method is 4×10-7mol·L-1 and RSD is 2% (for c=5×10-7mol·L-1).The method has been applied to the determination of thiourea in white grape wine.
