“…[9] The aim of the ultrafiltration process is to recover or concentrate some valuable substances from a solution; this is common practice in the chemical and pharmaceutical industries. [10] Another application consists in the removal of undesirable products such as particles, colloids, high molecular weight materials, heavy metals, [11][12][13] bacteria and viruses [14,15] from an effluent stream in order to obtain more purified water.…”

Collagen is one of the predominant proteins found in all multicellular animals. In this paper, the performance of the ultrafiltration process (UF) for concentrating the collagen protein was studied by performing batch experiments using a membrane module with an effective area of 28 cm 2 and equipped with a regenerated cellulose membrane with a molecular weight cutoff of 5 kDa. The feed solution consisted of aqueous solutions of bovine collagen hydrolysate with a molecular weight of 10 kDa. The effects of feed concentration (1%, 2%, 3%, 4%, and 5%) on the performance were determined. The optimum operating conditions were: a transmembrane pressure of 5 bar and a temperature of 25 C. The results showed that the permeability decreases with the increase of the volumetric concentration factor (VCF) for all five concentrated solutions of collagen tested. Also, the rejection of proteins increases with the increase in the concentration of the collagen solutions. The study confirms that the clogging phenomenon was dependent on the increase of concentration. Further, a mathematical modeling of fouling mechanism was analyzed based on Hermia's model. The concentration of the collagen solutions was also highlighted by viscosity measurements.

“…The complexes are very stable and contribute to greater antioxidant activity of flavonoids. Some of them in the presence of copper ions may also undergo the autooxidation process [7,8]. Besides, vegetables and fruits have also been shown to contain other antioxidant nutrients in addition to the well-known vitamins C and E and carotenoids that contribute significantly to their overall antioxidant capacity [9][10][11].…”

Anti-Oxidative Activity of Alcohol-Water Extracts from Field Horsetail (Equisteum arvense) in Elastomer Vulcanizates Subjected to Accelerated Aging Processes

et al. 2020

The article aimed to highlight the antioxidant potential of natural extracts obtained from Equisteum arvense in elastomer vulcanizatec made of natural rubber. Horsetail extracts were prepared using four solvent systems at different volume ratios: methanol–water (50/50 and 70/30) and ethanol–water (50/50 and 70/30), which were then lyophilized and added to the polymer matrix. A deep characterization of the obtained bio-additives was performed. The obtained vulcanizates were subjected to various aging processes: thermo-oxidative, ultraviolet and solar. Then, the resistance and susceptibility of vulcanizates to selected processes of accelerated, simulated degradation were determined based on the changes in the spatial structure (network nodes), material strength and physical properties (color). The research showed the presence of polyphenols in the extracts of horsetail, which resulted in their high anti-oxidative activity. Moreover, the extracts were able to absorb UV radiation. As a consequence, they were active additives that protected rubber vulcanizates against the damaging effects of the aging processes, securing their functional properties. Samples containing natural extracts were characterized by better stability of: mechanical strength parameters, the increase in cross-linking density and color changes after simulating aging processes in comparison with the control sample.

“…A value greater than 1 indicates metal bioaccumulation in the root. The higher this coefficient, the more the plant extracts the metal and fixes it to the root [7].…”

“…The translocation coefficient (TF) represents the ratio between the metal concentration in the aerial components (stem, leaves, or inflorescence) and the metal concentration in the plant root. In this case, a TF value greater than 1 also indicates the bioaccumulation in that part of the plant and this should be taken into account when assessing the risk of using the plant for therapeutic purposes [7].…”

Heavy metal toxicity in plants is well known due to their severe phytotoxic effects and also because of their capability to accumulate in vegetables. The use of aromatic plants in remediation techniques has increased in the context of environmental pollution issues, including metal soil contamination. Cadmium is knowed as a toxic and bio accumulative element provided by natural or anthropic sources. In this context, the paper presents a laboratory experimental study aiming to evaluate the accumulating and transfer behavior of Cd in the plant organs of Sinapis alba L. (white mustard) and in the presence of essential elements (Ca, Mg, Fe, Zn, Mn, Cu, Ni). The study involves a comparison between white mustard cultivated in unpolluted soil and in two Cd polluted soils at values above the alert (2.8 mg/Kg), respectively intervention threshold for soils with sensitive use (5.6 mg/kg) according to the legislation in force in Romania. While Cd accumulated predominantly in roots (TC values 1.46 and 2.22), its transfer to the stem and leaves was observed too, the TF values for the aerial part of the plant being greater than 1. Moreover, the study showed that certain elements (Zn, Ca, Mg, Mn) were found in higher concentrations in plants subjected to Cd pollution than in the control sample indicating antagonistic effects and Cd toxicity limiting. Other essential metals, such as Cu, Fe and Ni were found in lower concentrations in intoxicated plants compared to control plants. Their translocation from soil in plant organs could be reduced by the Cd toxicity. Contrariwise, the mobility of these elements from roots to leaves could support the tolerance effect of plants to Cd stress. The study allows us to consider that Sinapis alba L. aromatic plants are suitable for soil phytoremediation technologies used in Cd decontamination.
