摘要
硫磺是一种用途广泛的重要化工原料,砷含量是硫磺质量分级的重要参数。本文对硫磺砷含量测定中溶样方法 -硝酸氧化法、硫化铵法、过氧化钠法、硝酸压力溶弹法、氧弹燃烧法与测定方法——催化极谱法、砷钼蓝比色法、氢化物-原子荧光光谱法、氢化物-原子吸收光谱法、石墨炉原子吸收法进行概述,以便于测定时根据情况并结合其优缺点选择合适的方法。
Sulfur was a versatile chemical raw materials, and the arsenic content was an important parameter of the sulfur quality grading. Methods for dissolving sulfur arsenic content determination -nitric acid oxidation, ammonium sulfide, sodium peroxide, the pressure dissolved nitrate bomb method, oxygen bomb combustion method and measuring method- catalytic polarography, arsenic and molybdenum blue colorimetric, hydride -atomic fluorescence spectrometry, hydride generation- atomic absorption spectrometry, graphite furnace atomic absorption spectrometry were overviewed for selecting the appropriate method according to its advantages and disadvantages and the measurement conditions.
