“…In order to reduce the amount of pollutants in the water, an attempt was made to produce adsorbents from invasive plants (Nguyen et al, 2022). Eupatorium adenophprum spreng was used as adsorbent, which works mainly through ion exchange, for removing copper from an aqueous solution (Fan et al, 2022) and A. altissima sawdust biosorbent for removing the Acid Yellow 29 present in the wastewater (Rahman et al, 2021). Almeida et al (2021) obtained polyelectrolytes from the woody debris of A. altissima and Acacia dealbata and used them in a flocculation process of an effluent from olive oil mill.…”

Invasive plant species may cause not only several health problems, but also economic and environmental negative impacts – a gradual decrease of biodiversity and decline of soil fertility, issues that have recently come into the attention of several organizations including the research ones, in order to limit the spread of such species. The control methods of invasive species are often effective on the short term and include the probability of ecosystem imbalance over time, so that an efficient and sustainable management method that could add value to products or improve some industrial processes are strongly required. This study describes the potential of alien plants to maintain the quality of human life through different types of valorization, such as pharmaceutical, agriculture or food industry applications, energy production, paper technology and natural dyeing of various materials. Invasive plant species represent a global problem, accelerated by the current level of pollution and the rapidly-evolving society. Knowledge of chemical composition of different plant parts of invasive species, their potential for developing new products and their health effects will contribute to an efficient control, mechanical, chemical or biological, and an integrated management.

The Silica monolith particles (SMP) were prepared from Tetra-Methyl-Ortho-Silicate (TMOS) and characterized by Fourier transforms infrared (FTIR), Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and surface area analyzer. FTIR analysis showed the Si-O stretching confirming SMP formation. SEM analysis provided information about the mean diameter of SMP (1-5 µm). EDX confirmed the presence of silicon and oxygen in the SMP. Moreover, the calculated surface area for SMP was found to be around 367 m2/g, whereas BJH pore size distributed particles were 87.15 along with the total pore volume and pore radius of 0.073 cm3/g and 16.627 Å, respectively. Besides, the removal efficiency was found to be about 96%. Various kinetic equations were used to calculate the adsorption parameters. Overall, the results show that the most appropriate model for the kinetics data was the pseudo-second order kinetics model while the mechanism of adsorption was best explained by the Langmuir isotherm. The highest removal of Basic Red 5 dye after 120 min at 298 K was 576 mg/g. Moreover, the thermodynamics parameters (Enthalpy, Gibb’s energy, and Entropy) were also estimated. The ΔH° (0.995 kJ/mol) value depicted the endothermic nature of the process. The non-spontaneous aspect of the process was evident from the ΔG° values which were 60.431, 328.93, and 339.5 kJ/mol at 293, 303, and 313 K, respectively. From the high removal efficiency value, it can be concluded that the prepared adsorbent can be a potential adsorbent in the reclamation of dyes from wastewater.

“…These techniques are ineffective or extremely expensive, especially when wastewaters contain a relatively low concentration of metals (1–100 mg/L) dissolved in a large volume of water [ 8 ]. The utilization of biological objects is currently receiving wide attention because of their abundant availability, high removal capacity, eco-friendly nature, and low operating costs [ 5 , 9 , 10 ]. Microorganisms are capable of regulating metal ions and reducing their toxicity through various mechanisms [ 11 ].…”

Cyanobacteria-mediated wastewater remediation is an economical, efficient, and eco-friendly technology. The present work deals with the bioaccumulation performance of Arthrospira platensis (Spirulina) grown for four cycles in a medium containing nickel mono- and polymetallic synthetic effluents. The metal uptake by spirulina biomass was evaluated using neutron activation analysis. The effects of effluents on biomass production, protein, and phycobiliprotein content were assessed. Metal accumulation in the biomass depended on the effluent composition and metal ion concentrations. Nickel accumulation in the biomass was directly proportional to its concentration in effluents, and maximum uptake (1310 mg/kg) was attained in the Ni/Cr/Fe system. In the same system, biomass accumulated 110 times more chromium and 4.7 times more iron than control. The highest accumulation of copper (2870 mg/kg) was achieved in the Ni/Cu/Zn/Mo system and zinc (1860 mg/kg)—in the Ni/Cu/Zn/Sr system. In biomass grown in the media loaded with nickel and also chromium, iron, copper, strontium, zinc, and molybdenum, a decrease in productivity (on average by 10%) during the first cycle of cultivation and moderate reduction of protein content (by 15–27%) was observed. The presence of metals in the cultivation media inhibited phycobiliprotein synthesis, especially of phycocyanin, and promoted the synthesis of allophycocyanin. The maximum reduction of phycocyanin content was 77%, and the increase of allophycocyanin content—by 45%. Arthrospira platensis may be deemed as bioremediation of nickel-polluted wastewaters of complex composition.
