Background:

Novobiocin is an antibiotic requiring effective purification methods.
Active carbons are widely used adsorbents in chemical processes.

Purpose of the Study:

To investigate the adsorption of novobiocin from organic solutions using two types of active carbons (A and B).
To evaluate the impact of solvent type and composition on novobiocin adsorption.
To assess the efficacy of active carbon A for purifying novobiocin acetone extracts.

Main Methods:

Studying the adsorption of novobiocin from various organic solvents using active carbons A and B.
Analyzing the influence of solvent properties on adsorption capacity.
Evaluating the performance of active carbon A in removing impurities from novobiocin acetone extracts.
Investigating the adsorption of sodium novobiocin from water-acetone mixtures.

Main Results:

Adsorption levels were dependent on the organic solvent's nature.
Active carbon B demonstrated significantly higher novobiocin adsorption than active carbon A.
Active carbon A proved effective in purifying novobiocin acetone extracts.
The composition of water-acetone binary solutions influenced sodium novobiocin adsorption.

Conclusions:

The choice of active carbon and solvent is critical for efficient novobiocin adsorption.
Active carbon B is a more effective adsorbent for novobiocin compared to active carbon A.
Active carbon A can be utilized for the purification of novobiocin from acetone extracts.
Binary solvent composition plays a key role in the adsorption of sodium novobiocin.
