Air quality - determination of sulfur dioxide in a ambient air - tetrachlomercurate, pararosaniline
空氣質量二氧化硫的測定四氯汞鹽鹽酸副玫瑰苯胺比色法Hygienic determination method of sulfur dioxide in air of residential areas - tetrachloromercurate - pararosaniline spectrophotometric method
居住區大氣中二氧化硫衛生標準檢驗方法四氯汞鹽鹽酸副玫瑰苯胺分光光度法Abstract : 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:以甲醛緩沖溶液吸收-鹽酸副玫瑰苯胺分光光度法測定空氣中的二氧化硫，方法靈敏度高，選擇性好，避免了使用含汞的吸收液，但如果實驗條件控制不好，試劑空白值及標準曲線的斜率就會不符合《空氣和廢氣監測分析方法》中規定的值，本文著重從操作技巧方面對二氣化硫測定的實驗室質量控制進行分析，僅供參考。
