Description
Известен способ определени смолы в сточных водах путем калориметрии с применением в качестве экстрагента дл извлечени смолы бензола.There is a known method for determining tar in wastewater by calorimetry using benzene as extractant for extracting tar.
Примен емый по известному способу бензол вл етс взрыво- и огнеопасным веществом , довит (ПДК-0,02 мг/л), обладает большой летучестью паров, способен экстрагировать фенолы из сточных вод, в результате чего снижаетс точность анализа.Benzene used by a known method is an explosive and flammable substance, Dovit (MAC-0.02 mg / l), has a high volatility of vapors, and is capable of extracting phenols from wastewater, as a result of which the accuracy of the analysis is reduced.
С целью устранени этого, предложен способ определени смолы в сточных водах путем калориметрии с применением в качестве экстрагента дл извлечени смолы четыреххлористого углерода.To eliminate this, a method has been proposed for determining tar in wastewater by calorimetry using carbon tetrachloride as an extractant to extract the resin.
Это отличие дает р д преимуществ по сравнению, с ранее известным способом. Четыреххлористый углерод негорюч в сравнении с бензолоаЧ, менее токсичен (ПДК-0,05 мг/л),This difference gives a number of advantages in comparison with the previously known method. Carbon tetrachloride is incombustible in comparison with benzolac, less toxic (MAC-0.05 mg / l),
обладает большим удельным весом, чем вода , и поэтому в момент проведени анализа находитс под водой, в результате чего значительно уменьшаетс его выделенне в атмосферу . По отношению к фенолу вл етс худшим экстрагентом, чем бензол, в результате чего повышаетс точность анализа но сравнению с известным способом.has a higher specific gravity than water, and therefore at the time of analysis is under water, as a result of which its release to the atmosphere is significantly reduced. With respect to phenol, it is a worse extractant than benzene, as a result of which the accuracy of the analysis is improved compared with the known method.
Предмет изобретени Subject invention
Способ количественного определенн содержани смолы в сточных водах путем калориметрии с применением в качестве экстрагентов органических растворителей, отлнчающ и и с тем, что, с целью более безопасного проведени аналнза, а также с целью повышени точности, в качестве экстрагента дл извлечени смолы используют четыреххлористый углерод.The method of quantitatively determined resin content in wastewater by calorimetry using organic solvents as extractants is excellent, and so that carbon tetrachloride is used as an extractant for a safer analyzing, as well as to improve accuracy.
