“…The results show that increasing the LIX 84 concentration from 0.02 to 0.2 M resulted in an increase in copper extraction from 30 to 74%. These results align with the research conducted by Hao and Ho [39], who suggest that higher carrier concentrations enhance the extraction capacity, enabling a greater partitioning of copper into the organic membrane phase. In addition, the result shows that liquid membrane viscosity increases from 55.4 to 75.1 cP with the increase of LIX 84 concentration as depicted in Figure 4.…”

Extensive research has been conducted to address the growing global demand for copper by exploring effective methods of extraction and recovery across various industries. The emulsion liquid membrane (ELM) has emerged as a viable option for efficiently extracting and recovering metals from waste solutions. Due to its advantageous features, the extraction and recovery of copper from a simulated copper solution was investigated. In the ELM, various parameters can affect the stability and efficiency of copper extraction which include agitation speed, treat ratio (TR), stripping agent, and carrier concentration. However, certain parameters such as homogenizer speed, emulsification time, surfactant concentration, extraction time, and pH of the simulated feed solution were kept constant in this study. The most favourable parameters for achieving maximum copper extraction and recovery were determined such as TR of 1:3, agitation speed (250 rpm), LIX 84 (0.2 M) in kerosene as the carrier, and H2SO4 (0.5 M) as the stripping agent. Using these conditions, approximately 74% of the copper was extracted while 37% was recovered with an acceptable ELM stability indicated by a 20% membrane swelling. This research demonstrates the significant potential of the ELM process for extracting copper from wastewater generated by various industries.

Aims The use of phytochemicals to improve the effectiveness of antibiotics is a promising strategy for the development of novel antimicrobials. In this study, the antibiofilm activity of perillyl alcohol and hydrocinnamic acid, both phytochemicals present in several plants, and two antibiotics from different classes (amoxicillin and chloramphenicol) was tested, alone and in combination, against Escherichia coli. Methods and results Each molecule was tested at the minimum inhibitory concentration (MIC), 5 × MIC, and 10 × MIC, and characterized concerning biomass removal, metabolic inactivation, and cellular culturability. The highest percentages of metabolic inactivation (88.5% for 10 × MIC) and biomass reduction (61.7% for 10 × MIC) were obtained with amoxicillin. Interestingly, for 5 × MIC and 10 × MIC, phytochemicals provided a total reduction of colony-forming units (CFUs). Dual and triple combinations of phytochemicals and antibiotics (at MIC and 5 × MIC) demonstrated high efficacy in metabolic inactivation, moderate efficacy in terms of biomass reduction, and total reduction of cellular culturability for 5 × MIC. Conclusions The results demonstrated the antibiofilm potential of phytochemicals, highlighting the advantage of phytochemical/antibiotic combinations for biofilm control.
