摘　　要：为建立化学蒸气发生-原子荧光光谱法测定皮革和纺织品中可溶性痕量镉的方法,研究了还原剂浓度、酸度、催化剂浓度、共存元素以及仪器条件等主要因素对测定的影响.选择了最佳试验条件,检出限为O.8ng/g,加标回收率在95％～107％之间,能满足国际标准规定限量的测定要求.The soluble trace Cd in the textile fabric and leather was determinated by chemical vapor generation and atomic fluorescence spectrometry. The effects of concentrations of re-ductant and catalyst, acidity, coexisting elements and operating conditions were studied. The results obtained under optimum conditions show that the detection limit is 0. 8 ng/g and the addition recovery is between 95% and 107%.
