Study of bentonite-sorbent isotherm

Methods 
 
Dilatometry is a device that allows you to 
measure the change in gel volume depending on 
time, the results obtained allow you to study the 
kinetics of gel formation. 
X-ray diffractometry (XRD). The phase composition 
of sorbent samples synthesized at different 
temperatures has been studied by X-ray 
diffractometry. The X-ray diffractometer (XRD) of 
Empyrean, Malvern Panalitical (Germany) was 
used for the X-ray analysis of the samples. The 
Emrugeap Malvern panalytic X-ray diffractometer 
performs complex functions, such as performing 
quantitative phase analysis in phase transfer mode 
using a wide dynamic range of hybrid architectures 
Pixcel3D and Galipix3D, evaluating amorphous 
components, 
determining 
clusters 
and 
nanocomposite sizes.

Quantitative 
and 
qualitative 
phase 
analysis: to study the phase composition of 
sorbents, CuKα radiation was used (β-filter, Cu, 
current mode 1.5406 A ° and voltage supplied to 
the pipe, respectively, 30 mA and 30 kV), with a 
diode step of 0.02° in 4 °/min, with a constant 
rotation speed (corresponding to ω/2 θ). And the 
scanning angle was changed from 0° to 90°. When 
recording experiments, a rotating camera was 
used, the rotation speed of which was 30 rpm. The 
phase composition of the sorbent samples was 
analyzed using X-ray diffractograms by a semi-
quantitative method in which the intensity 
coefficients based on calibration standards were 
performed in accordance with the Сu radiation 
based on the I/Ic ratio.
