The preparation of biological phenolic resin (PF) with green recyclable biomaterials instead phenol is a research hotspot for solving current resource and environmental problems. In this study, on the basis introducing lignin into system, daidzein renewable rigid structure was selected to modify lignin-based (LPF), improvement mechanical thermal properties modified under different substitution ratios studied. friction materials were prepared daidzein-modified (D-LPF) as matrix binder, their effects mechanics wear investigated. results show that when proportion replacing 12%, highest Tp can reach 152.4 °C, Tg D-LPF resins significantly higher than those PF LPF.

This study investigates the kinetics and equilibrium of phenolic derivative detoxification from aqueous solutions using activated carbon derived coconut husk (CHAC). Phenolic compounds, prevalent in industrial wastewater, are highly toxic to humans aquatic life. The removal efficiency 4-Nitrophenol (PNP) 4-Chlorophenol (PCP) was examined batch adsorption experiments under varying conditions including adsorbent dose, contact time, initial concentration, temperature. Coconut chemically characterized for its properties. optimal dose PNP determined be 0.2 g, achieving a maximum capacity 64.65 mg/g after 120 minutes. Adsorption data were fitted pseudo-first-order pseudo-second-order kinetic models understand mechanism. results indicated that onto CHAC followed model, suggesting chemisorption as dominant process. findings demonstrate can an effective sustainable removing derivatives offering potential solution environmental detoxification. Further studies on isotherm thermodynamics recommended optimize process large-scale applications.
