Examples
- 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。 - In the view of hydrolyze coating way , ph value , treating temperature , concentration of premonitory matter solution , buffer solution amount and premonitory matter amount affect the coat layer forming mainly . according to the results of experiments , the best technical condition is that ph = 6 . 5 , [ al3 + ] = 0 . 064mol / l , t = 343k , vbugersoiution = 40ml
水解包覆工艺改性研究结果表明： ph值，处理温度，覆层前驱物溶液的浓度、缓冲溶液加入量和覆层前驱物加入量这几个因素对石墨表面覆层形成存在重要影响。
