查询词典 sulfur black

The method of using formaldehyde buffer solution a b sorption-hydrochloric pararosaniline spectrophotometry to determine sulfur diox ide in air has higher sensitivity and good selectivity,and prevents from adoptin g mercurial absorbent.But the conditions in lab are not well controlled,the v alue of reagent blank and standard curvilinear slope can't accord with the one s tipulated in"Methods for Air and Waste Gas Monitoring and Analysis".Some opra tional techniques for SO2 determination in lab are introduced for reference.

文摘：以甲醛缓冲溶液吸收-盐酸副玫瑰苯胺分光光度法测定空气中的二氧化硫，方法灵敏度高，选择性好，避免了使用含汞的吸收液，但如果实验条件控制不好，试剂空白值及标准曲线的斜率就会不符合《空气和废气监测分析方法》中规定的值，本文着重从操作技巧方面对二气化硫测定的实验室质量控制进行分析，仅供参考。
