Purified Na-CMC (a) and Ag
+
CMC¯, (b) films FTIR-spectrum results 
 
As can be seen in Figure 1-a, the maximum of the absorption band of the 
carboxymethyl anion in purified Na-CMC macromolecules is observed in the region of 
1620.92 cm
-1
. When sodium cations (Na
+
) were replaced by silver cations (Ag
+
) in the 
CMC macromolecule, the intensity of the absorption band increased to 1599.96 cm
–1
(Fig. 1-b). FTIR-spectroscopic studies have shown the possibility of synthesizing the 
Ag
+
CMC¯ polymermetalcomplex as a result of the interaction of Na-CMC with AgNO
3
salts.

Today, the use of modern innovative technologies plays an important role in 
increasing the productivity of the world's main agricultural crops, in particular, in 
creating effective tools that accelerate the growth of crops and increase their 
productivity. In the production of such tools, the use of materials with antimicrobial 
properties as well as simple, cheap and well-known structures as raw materials is of 
great importance. 
The following method was used to synthesize a complex compound based on CuSO
4
and cefotaxime. Aqueous and acetonitrile solutions of CuSO
4
(1.44 g, 0.003 mol) and 
cefotaxime (0.455 g, 0.001 mol) were mixed with a magnetic stirrer at a speed of 800 
revolutions per minute at a temperature of 400 
0
С for 1.5 hours. As a result, a pale blue-
green solution was obtained. This solution was left at room temperature for 5 days until 
crystals formed. 
Coordination compound obtained on the basis of copper (II) sulfate and cefotaximein 
order to compare with the theoretically calculated amounts of the elements in the 
composition, elemental analysis was carried out using the scanning electron microscope 
- energy dispersion analysis (SEM-EDT) method of the composition of the complex 
compounds obtained as a result of the reaction, and it was found that their amounts are 
compatible with each other. According to the results of SEM-EDT, a large number of 
peaks characteristic for the metal ion were noted, together with the formation of a 
complex of procaine hydrochloride with the metal ion and the change of the 
microstructure of the ligand. The degree of crystallinity of the new complex was also 
determined.
