In this work we have investigated possibilities for immobilization of lignin model
compounds (LMCs) as potential antimicrobial agents on activated charcoal particles aimed
for applications in wound dressings. LMC adsorption kinetics was determined for different
initial LMC concentrations (0.1, 0.5 and 1.1 mg ml-1) by using UV-visible spectroscopy over
24 h when the equilibrium was reached. LMC adsorption on charcoal particles was
confirmed by Fourier-transform infrared spectroscopy (FTIR). Adsorption kinetics was
successfully modeled by the pseudo-second order Lagergren model while the adsorption
isotherm at room temperature could be described by both Freundlich and Langmuir models
showing satisfactory agreements. The maximal capacity of activated charcoal particles for
LMCs according to the Langmuir model was 312.5 mg g-1. However, the immobilizates did
not exhibit antibacterial activity against Pseudomonas aeruginosa indicating the need for
further studies of LMC adsorptio...n mechanism with the specific aim to elucidate exact
compounds or functional groups responsible for antimicrobial action and their conformation
on activated charcoal.
