Summary: A two-step process was used to synthesize an organofunctionalized mesoporous silica, involving the co-condensation of a silylant agent on the surface of silica and the subsequent immobilization of Purpald at the organic termination of the silytant agent. The material was characterized to have NH2 groups, and the immobilization of the ligand was confirmed through Si-29 and C-13 nuclear magnetic resonance. The material exhibited a surface area of 370 m(2) g(-1). Batch adsorption experiments revealed the optimum pH conditions for Cu(II) and Cd(II) adsorption, and the adsorption behavior was described by the pseudo-second-order kinetic model and Langmuir model. Continuous-flow preconcentration experiments showed that the flow rate and eluent concentration affected the removal of Cu(II) and Cd(II), while the buffer concentration only affected the adsorption of Cu(II). Under optimized preconcentration conditions, the concentrations of Cu(II) and Cd(II) in various water samples could be determined. The adsorbent material exhibited reusability for at least 40 adsorption/desorption preconcentration cycles without efficiency loss.

This study focused on recovering copper from PCBs through electrowinning, using supercritical CO2 and cosolvents. The optimal current density for electrowinning was determined to be in the range of 250 to 540 A/m(2). With a current density of 250 A/m(2), pH 4, and temperature of 25 degrees C, a current efficiency of around 100% was achieved. The obtained deposit contained 95.97 wt% copper, recovering 40% of the copper in the solution within 300 minutes of electrowinning.

Summary: The aromatization of olive pomace oil with rosemary and basil using ultrasound-assisted maceration (UAM) was able to increase its bioactive potential. Results showed that UAM resulted in no significant difference in quality parameters and fatty acids compared to pure olive pomace oil, but led to a significant increase in total phenolic compounds, antioxidant capacity, and oxidative stability. Thus, ultrasound-assisted maceration is an efficient method to enhance the bioactive potential of olive pomace oil in a short time.
