Description

Изобретение относитс  к технике определени  удельной адсор бции жидкости, например воды, на поверхности дисперсных материалов и может быть использовано в агротехнических лаборатори х дл  оценки адсорбционных свойств грунтов.The invention relates to a technique for determining the specific adsorption of a liquid, such as water, on the surface of dispersed materials, and can be used in agrotechnical laboratories to evaluate the adsorption properties of soils.

Известен способ определени  удельной адсорбции жидкости в пористом или дисперсном материале путем сравнительных пикнометрических измерений плотности исследуемой и реперной жидкости в этом материале.A known method for determining the specific adsorption of a liquid in a porous or dispersed material by means of comparative pycnometric measurements of the density of the test and reference fluid in this material.

Однако по такому способу необходимо точно определить свободный объем пор дисперсного материала.However, by this method it is necessary to accurately determine the free pore volume of the dispersed material.

Предлагаемый способ повышает точность измерений. Дл  этого определ ют объем системы исследуема  жидкость-дисперсный материал дл  двух фракций материала с различной дисперсностью.The proposed method improves the accuracy of measurements. To do this, determine the volume of the system of the investigated liquid-dispersed material for two fractions of a material with different dispersion.

Адсорбци  жидкости на поверхности твердого материала приводит к изменению средней плотности жидкости в системе и тем самым к изменению полного объема системы . Величина этого изменени  пропорциональна величине поверхности твердого дисперсного материала. Производ  измерени  суммарного объема системы дл  двух различных фракций дисперсного материала (при полном погружении материала в жидкость), определ ют величину удельной адсорбции жидкости.The adsorption of a liquid on the surface of a solid material leads to a change in the average density of the liquid in the system and thus to a change in the total volume of the system. The magnitude of this change is proportional to the magnitude of the surface of the solid particulate material. By measuring the total volume of the system for two different fractions of the dispersed material (with full immersion of the material in the liquid), the value of the specific adsorption of the liquid is determined.

Приме р. Берут две фракции сухого материала различной дисперсности с предварительно определенной удельной поверхностью и заполн ют ими два пикнометра. На аналитических весах определ ют навеску сухогоPrimer p. Take two fractions of dry material of different dispersion with a predetermined specific surface area and fill them with two pycnometers. The analytical balance determines the weight of dry

материала в каждом пикнометре и затем заполн ют пикнометры с материалом исследуемой жидкостью. После этого определ ют навеску введенной в пикнометры л идкости и, зна  объем пикнометров, наход т ее удельную адсорбцию.the material in each pycnometer and then the pycnometers are filled with the material to be examined. After that, the weights of the liquid introduced into the pycnometers are determined and, knowing the volume of the pycnometers, its specific adsorption is found.
