A cleanup procedure is described for the determination of sulfamethazine in milk. The residue is diazotized and coupled with 1-naphthol. The diazotized sulfamethazine (SMZ) is accumulated on a mercury electrode by electrochemical adsorption and is then stripped cathodically. This method determines SMZ quantitatively at low parts-per-billion levels.
描述了一种用于测定牛奶中磺胺二甲嘧啶的净化程序。残留物经重氮化并与1-萘酚偶合。重氮化的磺胺二甲嘧啶（SMZ）通过电化学吸附积累在汞电极上，然后进行阴极溶出。该方法可在十亿分之几的低水平下对SMZ进行定量测定。
