This paper carries the determination of absorbency at λmax = 400 nm through generator hydrogen as an impetus, keeping amounts of neogenesis state hydrogen constant contact with concentrated sample of arsenic and making use of Ag + -PVA-EtOH-H2O as absorbent fluid of arsine.As a result, arsenic is linear with absorbency ranging from 0-1.8 mg / L, whose regression-line equation is A = 0.018 92 + 0.127 0C(mg / L).

用发生氢为动力,使浓缩砷样在锌柱内与大量新生态氢连续接触,砷化氢以Ag~+-PVA-Et OH-H_2O为吸收液,在λ_(max)400 nm处进行吸光度测定;砷在0~1.8mg/L范围内与吸光度呈良好的线性关系,其回归线方程为A=0.01892+0.1270C(mg/L)。

With the room temperature and 0.45 mol/L phosphoric acid medium, NO - 2 has a great catalysis on discoloration reaction of KBrO 3 oxidation bromocresol purple, establishing a new way of measuring NO - 2. After 12 min of reaction, NO - 2 is measured at 434 nm, with linearity range from 0.01~0.4 mg/L and at 25 °C its regression line equation is △A=1.0685C(mg/L)+0.0146 r=0.9980. The way is easy to handle and has high precision and selectivity, proved satisfying in measuring NO - 2 of meat products.
