Abstract
Изобретение относитс к определению дифференцированной карбонатности и позвол ет повысить точность при определении количества кальцита, доломита, магнезита в образце по ступенчатому повьшению давлени при воздействии на образец 0,5 - 6 об.% сол ной кислоты и механических колебаний. В интервале частот от 10 до 75 Гц определ етс кальцит, в интервале от 798 до 911 Гц - доломит, в интервале от 14700 до 16200 Гц - магнезит. 3 табл. MK 00 4ib о ср 4:The invention relates to the determination of differentiated carbonate content and allows to increase the accuracy in determining the amount of calcite, dolomite, magnesite in the sample by stepwise increase in pressure when the sample is exposed to 0.5-6% by volume of hydrochloric acid and mechanical vibrations. In the frequency range from 10 to 75 Hz, calcite is determined, in the interval from 798 to 911 Hz - dolomite, in the interval from 14,700 to 16,200 Hz - magnesite. 3 tab. MK 00 4ib about Wed 4:
Description
Изобретение относитс к аналитической химии, в частности к измерени м химического состава твердых тел, а именно к определению содержани и состава их карбонатной составл ющей ,The invention relates to analytical chemistry, in particular, to measurements of the chemical composition of solids, namely to the determination of the content and composition of their carbonate component,
Цель изобретени - повышение точности определени дифференцированной карбонатности.The purpose of the invention is to improve the accuracy of determining the differentiated carbonate content.
Пример . Навеску образца помещают в реакционный сосуд и герметизируют . Обрабатывают образец сол ной кислотой концентрацией 0,5 - 6 об,% при комнатной температуре и фиксируют начальное давление (объем) газа.An example. A sample of the sample is placed in a reaction vessel and sealed. The sample is treated with a hydrochloric acid concentration of 0.5–6 vol% at room temperature and the initial pressure (volume) of the gas is fixed.
Воздействуют на образец знакопеременными механическими колебани ми.The sample is acted upon by alternating mechanical vibrations.
ступенчато наращива частоту, и запи- 20 0,5% увеличивает врем экспериментаincreasing the frequency in steps and recording 20 0.5% increases the time of the experiment
сывают кривую давлени (объема) газа, добива сь ее стабилизации на каждом уровне.The gas pressure (volume) curve is plotted, until it stabilizes at each level.
При 2 об,% НС1 значени частот следующие, Гц: кальцит 10 - 57, доломит 798 - 911, магнезит 14700 - 16200.At 2 vol% HC1, the frequencies are as follows, Hz: calcite 10–57, dolomite 798– 911, magnesite 14700– 16200.
Градуировку выполн ют следующим образом.Calibration is performed as follows.
В реакционную камеру помещают навеску кальцита (доломита, магнезита) и обрабатывают ее сол ной кислотой. Воздейству на образец знакопеременными механическими колебани ми, наращивают частоту до полного завер- шени реакции. Верхнее значение частоты принимают за высоту ступени воздействи .A calcite sample (dolomite, magnesite) is placed in the reaction chamber and treated with hydrochloric acid. By acting on the sample by alternating mechanical vibrations, the frequency is increased until the reaction is complete. The upper frequency is taken as the height of the step of action.
При реализации способа изучают известн ки, доломиты и мергели сак без существенного повьшени точности При концентраци х выше 6% погрешност возрастает.During the implementation of the method, limestones, dolomites and marls without significant increase in accuracy are studied. At concentrations above 6%, the error increases.
