AB  - In this investigation, the possibility of wood waste (hardwoods such as oaks’ and alternatives’ staves from Balkan cooperage) revalorization for simultaneous cadmium removal and wastewater disinfection was examined. All samples were characterized in terms of their crystallinity index and crystallite size, amount of functional groups, and surface chemistry (determined by ATR-FTIR) as well as antibacterial activity. Mulberry is characterized by the lowest crystallinity index which can be ascribed to the highest crystallite size disabling crystallite denser packaging, while myrobalan plum has about 23% lower crystallite size that enables crystallite better packaging, thus resulting in a 42.4% higher crystallinity index compared to the mulberry. All oaks have a significantly higher amount of carboxyl groups compared to the alternatives (0.23-0.28 vs. 0.12-0.19 mmol/g). The adsorption experiments revealed that with increasing the initial cadmium concentration from 15 up to 55 mg/g, samples’ adsorption capacity increases by 89-220%. The equilibrium data fit well with the Langmuir isotherm model implying monolayer coverage of cadmium ions over a homogeneous wood surface. The relationship between the samples’ maximum adsorption capacities (ranged from 5.726 to 12.618 mg/g), their crystallinity index, and crystallite size was established. According to ATR-FTIR spectra, aldehyde, carboxyl, hydroxyl, and phenyl groups present on the wood waste surface are involved in Cd2+ adsorption which proceeds via the interplay of the complexation, cation-π interactions, and ion-exchange mechanisms. Mulberry and myrobalan plum showed about 89% and 80% of the total uptake capacity of cadmium within 60 min, while the equilibrium was attained after 240 min of contact time. Good compliance with pseudo-second kinetic order indicated that cadmium adsorption was mediated by chemical forces. Thermodynamic parameters revealed the spontaneous and exothermic character of cadmium ion adsorption onto mulberry and myrobalan plum. All studied samples provide maximum bacterial reduction (>99%) for E. coli and S. aureus. Wood waste from Balkan cooperage can be successfully used for simultaneous cadmium removal and wastewater disinfection.

AB  - Six ethanolic extracts, obtained from anise, fennel, lavender, sage, mint, white horehound and their mixture were directly applied onto cellulose (viscose) fabric to impart antimicrobial and antioxidant functionality for its potential use as a wound dressing. Antimicrobial activity of treated fabrics against gram-positive bacteria S. aureus and yeast C. albicans, as common skin pathogens, was determined by agar diffusion test. The most effective against both microorganisms was viscose with anise, fennel, and mint, whereby clear inhibition and suppression zones were detected. The oxidation of viscose, intended to improve sorption properties and consequently adsorption of extracts, increased the antimicrobial activity of viscose with a mixture of extracts. The antioxidant activity of fabric samples with extracts, determined by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay, was significantly higher when compared to the untreated viscose sample (2.38 %) and ranged from 11.82 % for viscose with fennel up to 87.71 % for viscose with sage. Oxidation of fabric before sorption of extracts mixture contributes to higher antioxidant activity (68.81 %). Direct impregnation of bioactive plants extracts onto the fabric represents low cost and simple method, which makes it suitable for obtaining eco-friendly, low-cost disposable medical textiles with the therapeutic and prophylactic role.
