Antibacterial powder coatings have attracted increasing attention with the awakening of people’s health awareness. Silver antibacterial agent has been widely used in coating system due to its superior stability and durability. However, silver ions problems excessive release rate tendency cause yellowing film. The addition Cu2+ Zn2+ can effectively alleviate these two phenomena. In this paper, ternary exchange kinetics Ag+, Cu2+, were studied provide a theoretical basis for synthesis LTA-Ag-Cu-Zn. reaction study shows that selectivity adsorption capacity LTA Ag+ is higher than Zn2+. thermodynamic analysis discovers highest between spontaneous. contrast, concentration-dependent. By establishing three-ion competitive curve, it found highest, copper zinc similar. These trends result from ions’ low hydration energy, small radius, strong electronegativity. This research lays groundwork developing high-performance LTA-Ag-Cu-Zn tri-ion agents.

In this work, gasification of hazelnut shells grains is carried out in a bench-scale rotary kiln by using air as gasifying agent at 800 °C. The producer gas directly treated thermal cleaning unit operating 800–1100 °C with the aim to reduce load contaminants. methods usually studied model compounds, whilst herewith behavior real investigated. Results indicate that high temperature CO2 reacts tar and particulate generate CO, thereby improving quality terms heating value, yield contaminants content. Benzene most abundant organic contaminant gas, concentration which significantly reduced upon treatment. For first time, gasifier lignocellulosic biomass feedstock integrated unit, providing experimental evidences about suitability for its integration unit. proposed approach could find application also when other types are adopted, although parametric study should be order fully understand reaction mechanism removal optimal operation conditions, function features.

This study investigates the adsorption of diclofenac (DCF) onto an olive leaf-derived adsorbent. The harvested leaves were washed, dried, and powdered then extracted with 80% ethanol. extraction was filtered, washed sodium hypochlorite, ethanol, dried. material activated using hydroxide, phosphoric acid, dead sea water, for DCF from contaminated water being investigated. Various operational parameters such as dosage, contact time, concentration, pH systematically varied to understand their influence on efficiency. kinetics followed pseudo-second-order kinetics. Isothermal studies revealed that process conforms well Freundlich isotherm, suggesting multilayer a heterogeneous surface. Thermodynamic analysis indicated is spontaneous exothermic. Morphological completed SEM data demonstrated transformation in porous structure adsorbent, indicating effective pore occupation by molecules post-adsorption. Overall, results demonstrate effectiveness adsorbent efficiently removing aqueous solutions.

Natural zeolite is commonly used as an adsorbent for road dust suppression due to its excellent moisture absorption properties. However, during the formation process, natural tends accumulate some water, organic impurities, and metal cations that occupy pore channels cavities, thereby blocking passage of water molecules hindering their adsorption. This study aims improve weak rate capacity asphalt mixtures caused by clogged pores impurities in zeolite. To achieve this different concentrations salt solutions (NH 4 Cl, NaCl, MgCl 2 , CaCl ) are modifiers treatment Scanning electron microscopy Fourier transform infrared spectroscopy interface functional group changes between modified substrate mixture. The nitrogen adsorption/desorption curves with dosages were obtained using a adsorption instrument. Based on this, parameters such specific surface area volume calculated BET BJH methods. A macroscopic test was further conducted evaluate effect mixture PM 10 . results show significantly improved. 20wt.%CaCl modification performs best, can reach up times Compared mixture, increased 16.52%, 44.9%. addition powder improves performance When dosage reaches 80%, peak, improvement 16.34%.
