Indicating compound for determining hydroquinone |
| abstract |
The invention relates to analytical chemistry, in particular the determination of hydroquinone, the main raw material of chemical and polymer production. To do this, use an indicator mass containing 0.2-0.7% of the dye - diazotized sofranin T, on the filler - Sphereon P. This increases the accuracy and sensitivity of the analysis to 2 mg / m 3 versus 5 mg / cm 3 with an analysis error of 5 -7%. 2 tab. |
