Sažetak
Biodegradable polymers that have antimicrobial properties have a very wide application in medicine and medical materials and are often used as medical textiles (bedding and hospital towels) or consumables such as bandages, gauze, and wound dressings. Polymers that are produced by 3D printing can also be functionalized with nanoparticle coatings to obtain antimicrobial properties. These materials can therefore be used as catheters, consumables, coatings and bags. In this work, the TLC method was applied to analyze 60 different metal ions in the antimicrobial coating of samples prepared in the laboratory. The stationary phases tested were 31 different preprepared cellulose and silica gel, polyamid and Al2O3, and the mobile phase consisted of various developers containing mixtures of inorganic and organic solvents (such as acetonitrile, acetyl acetone, butanol, triethylamine, ethylenediaminotetraacetic acid, hydrochloric acid, water, etc.). The optimal system that detected all metal ions consisted of silica gel as a stationary phase, while the mobile phase contained a solvent mixture of acetonitrile: hydrochloric acid: water, a volume of 24 mL in a volume ratio of 60.00: 19.17: 20.83. Sample detection was performed using a UV cabinet and during the detection the separation parameters (RF, Rs and others) of known standard solutions of metal ions were determined, which were then used in the detection of analytes in an unknown samples.
