摘要

本研究考察了羟基磷灰石（HAP）和磁性HAP改性松子壳生物炭（PB）对阴离子合成染料（即Eriochrome Black T （EBT）和刚果红（CR））的吸附和去除的影响。HAP和磁性HAP改性显著改善了孔隙结构。光大通信和CR铅的去除效率,PBH,和PBH-Fe如下:(i) Qmax光大通信:PB = 1.24 毫克/ g, PBH = 46.06 毫克/克,PBH-Fe = 40.77 毫克/克,和(2)Qmax CR: PB = 1.18 毫克/ g, PBH = 62.96 毫克/克,PBH-Fe = 57.89 毫克/克。这是因为PB对EBT和CR的去除主要受氢键相互作用的支配，而PBH和PBH- fe的吸附主要受静电相互作用和离子交换作用的支配，其中包括HAP的磷酸盐和钙组分。此外，PBH-Fe吸附EBT和CR后的磁性能使其回收率超过90% %。综上所述，磁性HAP改性是一种实用有效的方法，可以提高PB在阴离子合成染料去除中的去除率和可重复利用性。

Hydroxyapatite and magnetic hydroxyapatite biochar from pine nut husks for anionic azo dye adsorption: Performance and reusability assessment

This study examines the effects of hydroxyapatite (HAP) and magnetic HAP-modified pine nut husk biochar (PB) on the adsorption and removal of anionic synthetic dyes [i.e., Eriochrome Black T (EBT) and Congo Red (CR)]. HAP and magnetic HAP modification significantly improved the pore structure. The removal efficiency of EBT and CR on PB, PB_H, and PB_H-Fe was as follows: (i) Q_max of EBT: PB = 1.24 mg/g, PB_H = 46.06 mg/g, PB_H-Fe = 40.77 mg/g, and (ii) Q_max of CR: PB = 1.18 mg/g, PB_H = 62.96 mg/g, PB_H-Fe = 57.89 mg/g. These results demonstrate that HAP modification substantially enhances the adsorption capacities of EBT and CR. This is because the removal of EBT and CR by PB was primarily governed by hydrogen bonding interactions, whereas adsorption by PB_H and PB_H-Fe was attributed to electrostatic interactions and ion exchange involving phosphate and calcium components of HAP. In addition, PB_H-Fe exhibited a recovery rate exceeding 90 % due to its magnetic properties after the adsorption of EBT and CR. Overall, magnetic HAP modification presents a practical and efficient approach to enhance both the removal and reusability of PB for anionic synthetic dye removal.
