尿砷测定是衡量人体砷吸收情况的重要指标,可以通过尿砷浓度的测定推测被检者近期砷摄入的情况。尿砷的测定方法有银盐法、氢化物发生—原子吸收光谱法、原子荧光法、石墨炉原子吸收分光光度法等方法。银盐法测定尿砷,因其所用仪器价格低而被广范采用,但由于其操作环节较多,稍
Determination of urinary arsenic is a measure of human arsenic absorption of an important indicator of the concentration of urine can be determined by the determination of arsenic was seized recent arsenic ingestion. Determination of urinary arsenic silver salt method, hydride generation - atomic absorption spectrometry, atomic fluorescence spectrometry, graphite furnace atomic absorption spectrophotometry and other methods. Determination of urine arsenic silver salt method, because of the low price of the instruments used by a wide range of applications, but because of its more operational aspects, slightly
