All activities require drinking water. The existence of waste makes water unfit for consumption. Phenol waste is one example of waste that is often found. The toxic and corrosive nature of phenol is very dangerous for life, so its presence must be considered. The adsorption process was carried out using NiAl and ZnAl layered double hydroxides composites with biochar to eliminate the presence of phenol waste The adsorption process was carried out using NiAl and ZnAl layered double hydroxydes materials which were composited with biochar to eliminate the presence of phenol waste. NiAl-Biochar and ZnAl-Biochar composites were successfully prepared, as determined by XRD, FTIR, SEM, and BET analyses. NiAl layered double hydroxide surface area grew from 92.683 to 438.942 m2/g while ZnAl layered double hydroxide surface area increased from 9.621 to 58.461 m2/g. pHpzc of material is between 5.1 and 9.4. Optimal pH of NiAl and ZnAl layered double hydroxide is 3, optimum pH of NiAl-Biochar and ZnAl-Biochar is 5, and optimum pH of Biochar is 7. All kinetic and isotherm models for all materials were pseudo-second-order and Freundlich, respectively. NiAl-Biochar and ZnAl-Biochar have maximal adsorption capacities of 74.62 mg/g and 52.91 mg/g, respectively. The material's reusability indicates that NiAl-Biochar has superior qualities and may be reused for up to five cycles, followed by ZnAl-Biochar, NiAl layered double hydroxide, ZnAl layered double hydroxide, and Biochar.

“…The phenolic compounds are important organic pollutants produced in many chemical processes, such as petroleum refining, coal coking, gas refining, papermaking, and many fine chemical synthesis. , Phenol and its derivatives have the potential toxicity of carcinogenesis, teratogenesis and mutation and can be accumulated in the environment, which will cause great harm to human health, water environment ecology, and agriculture. − As a result, a large amount of phenol-containing wastewater from different chemical processes has been listed as toxic hazardous environmental pollutants. Therefore, the treatment of phenol-containing wastewater has become an important research topic widely concerned by both academia and industries …”

This study provides a comprehensive analysis of the adsorption behaviors and mechanisms of phenol and catechol on magnetic graphene oxide (MGO) nanocomposites based on adsorption experiments, mathematical models, and molecular simulations. Through systematic experiments, the influence of various parameters, including contact time, pH conditions, and ionic strength, on the adsorption efficacy was comprehensively evaluated. The optimal contact time for adsorption was identified as 60 min, with the observation that an increase in inorganic salt concentration adversely affected the MGOs’ adsorption capacity for both phenol and catechol. Specifically, MGOs exhibited a superior adsorption performance under mildly acidic conditions. The adsorption isotherm was well represented by the Langmuir model, suggesting monolayer coverage and finite adsorption sites for both pollutants. In terms of adsorption kinetics, a pseudo-first-order kinetic model was the most suitable for describing phenol adsorption, while catechol adsorption conformed more closely to a pseudo-second-order model, indicating distinct adsorption processes for these two similar compounds. Furthermore, this research utilized quantum chemical calculations to decipher the interaction mechanisms at the molecular level. Such calculations provided both a visual representation and a quantitative analysis of the interactions, elucidating the underlying physical and chemical forces governing the adsorption phenomena. The findings could not only offer crucial insights for the treatment of coal industrial wastewater containing phenolic compounds with bridging macroscopic observations with microscopic theoretical explanations but also advance the understanding of material–pollutant interactions in aqueous environments.
