摘要 锑是一种广泛分布的有毒元素,许多研究证明锑对人体及生物具有毒性及致癌性,由于锑矿的开采和加工以及自然过程的影响,环境水样中锑污染日趋严重,而人体及生物对锑的摄取,一般来自饮用水、空气等,因此有效、快速、灵敏的测定环境水样中的锑具有实际的意义。目前检测锑的常用方法有原子吸收法、光度法、荧光法以及容量法等,尽管这些方法也有许多优点,但有些因仪器价格昂贵而影响其推广。 A new FI inhibitory kinetic spectrophotometric method using the redox reaction between potassium bromate and 2-[ 2' - (5-Nitro-pyridylazo) ] chromotropic acid ( 5-NO2-PACA ) is proposed for the determination of trace antimony (III). In phosphoric acid medium and reaction temperature at 50cC ,the linear range is 0~0. 36μg·mL^-1 and the detection limit is 9. 6 × 10^-6g· L^-1 The relative standard deviation is 0. 59%. 20. 2 samples can be analysed per hour. Combined with the ASS,the method has been applied to the determination of trace antimony(HI) in the samples of natural waters. The comparison and recovery tests have also been carried out, and satisfactory results are obtained.
