| titleOfInvention | A kind of method of sulfur trioxide and sulfuric acid concentration in measurement workplace air |
| abstract | The method of sulfur trioxide and sulfuric acid concentration in a kind of measurement workplace air of the present invention, include the steps that a preparation mix reagent, mix reagent is made of dehydrated alcohol, barium chloride solution and polyethylene glycol, dehydrated alcohol, barium chloride solution, polyethylene glycol volume ratio be 1:2:0.2~0.7；The step of one preparation hydrochloric acid solution；Sample solution, mix reagent and hydrochloric acid solution mixing, measure sample absorbance；It is compared by the absorption values and standard curve of acquisition, obtains sulfur trioxide and sulfuric acid concentration in workplace air.By the present invention in that using polyethylene glycol as concentration of hydrochloric acid used in stabilizer, the proportion for changing barium chloride mix reagent, optimization and measuring the mixed reaction time of preceding reagent, make during measuring sulfur trioxide and sulfuric acid, the standard curve of preparation is linearly more preferable, the solution absorbance stable time is long, and properties are able to satisfy the requirement of sulfur trioxide and sulfuric acid in measurement air. |
