Activated carbon from the shell of the cashew of Para (SCP) was produced by chemical activation with ZnCl using the ratio of SCP: ZnCl₂ 1.0:1.5 at 700 °C. The prepared activated carbon (SCP700) was used for the removal of two emerging contaminants, 4-bromophenol (4-BrPhOH) and 4-chloroaniline (4-ClPhNH₂) that are primarily employed in the industry. Different analytical techniques were used to characterize the activated carbon. From the N₂ adsorption–desorption isotherms were obtained the specific surface area of 1520 m² g⁻¹ and total pore volume of 0.492 cm³ g⁻¹. The functional groups were identified by the FTIR technique and quantified by modified Boehm titration. The results revealed the bearing of several functional groups on the SCP700 surface, which may utterly influence the removal of the emerging contaminants. The equilibrium experiments showed that the maximum uptaken capacities (Q_max) achieved at 45 °C were 488.2 (4-BrPhOH) and 552.5 mg g⁻¹ (4-ClPhNH₂). The thermodynamic parameters demonstrated that the processes of 4-BrPhOH and 4-ClPhNH2 adsorption are exothermic, spontaneous, energetically suitable, and the magnitude of ΔH° is compatible with physisorption. The mechanism of the adsorption of the emerging contaminants onto the carbon surface is dominated by microporous filling, hydrogen bonds, π-stacking interactions, and other Van der Waals interactions. The use of activated carbon for the treatment of industrial synthetic wastewater with several inorganic and organic molecules commonly found in industrial effluents showed a very high percentage of uptaking (up to 98.64%).

通过在700°C下使用SCP：ZnCl ₂ 1.0：1.5的比例用ZnCl进行化学活化，产生了对位（SCP）腰果壳中的活性炭。制备的活性炭（SCP700）用于去除两种主要在工业中使用的新兴污染物4-溴苯酚（4-BrPhOH）和4-氯苯胺（4-ClPhNH ₂）。使用了不同的分析技术来表征活性炭。从N ₂吸附-解吸等温线获得比表面积1520 m ² g ^-1和总孔体积为0.492 cm ³  g ^-1。通过FTIR技术鉴定官能团并通过改进的Boehm滴定法定量。结果显示SCP700表面上带有多个功能基团，这可能完全影响对新兴污染物的去除。平衡实验表明，在45°C下获得的最大吸收容量（Q _max）为488.2（4-BrPhOH）和552.5 mg g ^-1（4-ClPhNH ₂）。热力学参数表明4-BrPhOH和4-ClPhNH2的吸附过程是放热的，自发的，在能量上合适的，并且ΔH°的大小与物理吸附相容。微孔填充，氢键，π堆积相互作用和其他范德华相互作用决定了新兴污染物在碳表面上的吸附机理。活性炭用于处理工业废水中常见的几种无机和有机分子的工业合成废水的吸收率非常高（高达98.64％）。
