In the boron medium of ph = 4. 5, the complex of mo ( vi ) - ars - cpc, can be collected on nitrocellulose membrane. the complex and the filter are dissolved in a small volume of dmso, and the absorbance of the resulting solution is measured by means of spectrophotometric method at 490 nm wavelength against the reagent blank. the detection limits better than 1. 2ug / l can be achieved
5的hac寸aac緩沖溶液中， mo （ vi ）與酋素紅s （ ars ）以及澳代十六烷基毗陡（ cpc ）形成的三元絡合物能夠被硝化纖維微孔濾膜定量富集，富集膜溶解在小體積的二甲亞礬中，於490run處以試劑空白為參比測定吸光度。 -
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。 -
The complex and the filter are dissolved in a small volume of dmso, and the absorbance of the resulting solution is measured by means of spectrophotometric method at 545nm wavelength against the reagent blank. the detection limits better than 1. 0 u g / l can be achieved
50倍富集時，方法的檢出限為0 85pg l 。以上兩種方法應用於分析天然水以及礦泉水中的mo （ vi ）和的o ） ，回收率好，結果滿意。
