建立了肝中砷含量的电感耦合等离子体发射光谱检测法。考查了 HNO_3——H_2SO_4消化和马福炉高温灰化破坏有机质的方法,在193.695mm 波长下用电感耦合等离子体发射光谱测定,根据工作曲线法进行定量。结果回收率分别为:100.1%和101.2%,线性范围均为:0.1μg/ml～0.5μg/ml。该法操作简单,结果可靠,适合砷中毒肝含量检测,可作为司法鉴定常规捡验方法。 Arsenic content in liver was determined by inductively coupled plasma atomic emission spectrometry. The method of HNO_3 - H_2SO_4 digestion and muffle high temperature ashing destruction of organic matter was investigated. Inductively coupled plasma atomic emission spectrometry was performed at a wavelength of 193.695mm and quantified according to the working curve method. The recovery rates were 100.1% and 101.2%, respectively. The linear range was 0.1μg / ml ~ 0.5μg / ml. The method is simple, reliable, suitable for detection of arsenic poisoning liver, can be used as forensic identification of routine testing methods.
