管式炉燃烧-硫酸钡比浊法测定硼铁中低硫
Determination of low sulfur in ferro-boron by tube-furnace combustion-barium sulfate turbidimetry
【摘要】 用管式炉燃烧分离出硫 ,被过氧化氢水溶液吸收、氧化 ,在 0 0 8～ 0 1mol/L盐酸介质中 ,SO2 - 4与Ba2 + 生成BaSO4悬浮液 ,在 42 0nm处进行比浊。此方法简便 ,结果可靠 ,RSD =7 8%
【Abstract】 Separated sulfur burned by tube furnace was absorbed and oxidized by hydrogen peroxide in the medium of 0.08-0 10mol/L hydrochloric acid,a suspension of BaSO 4 was formed by the reaction between SO 2- 4 and Ba 2+ ,then it was determined at 420nm by turbidimetry The proposed method was easy to operate with reliable results,RSD=7.8%.
