In this study, bone chars were obtained from an alien aquatic species “devilfish” bones by pyrolysis of 500–800 °C. Bone chars were evaluated as a sustainable adsorbent of fluoride, and it was found pyrolyzed bone char at 500 °C adsorbed the most amount of fluoride. Thermodynamic parameters of fluoride adsorption on devilfish bone chars were estimated as ΔH° = 7.213 kJ mol⁻¹, ΔG° = 23.61 kJ mol⁻¹, and ΔS° = 103.4 J mol⁻¹ K⁻¹ indicating that adsorption is endothermic, spontaneous, and with a great affinity of fluoride on bone char. The fluoride desorption study showed that fluoride is desorbed from the material of 0.24 to 20.06%, so the adsorption is considered to be partly reversible. The regeneration of the bone char at 400, 500, and 600 °C was studied, and it was noted that its adsorption capacity decreases slightly, so it could be considered appropriate for the use in water treatment technologies. Adsorption of fluorides from drinking well water of a rural community with dental fluorosis problems and high levels of fluoride in water revealed that by increasing the amount of the bone char of 0.05 to 0.8 g, the disposal of fluoride increases from 69.1 to 98.7%. Lastly, it was established that the bone char synthesized from devilfish is a low-cost, viable, sustainable material to remove fluorides from water and represents an environmental management strategy of this alien species.

在这项研究中，骨炭是通过 500–800 °C 的热解从外来水生物种“魔鬼鱼”骨头中获得的。骨炭被评估为一种可持续的氟化物吸附剂，发现在 500°C 下热解的骨炭吸附的氟化物量最大。魔鬼鱼骨炭吸附氟化物的热力学参数估计为ΔH°  = 7.213 kJ mol ^-1、ΔG°  = 23.61 kJ mol ^-1和ΔS°  = 103.4 J mol ^-1  K ^-1表明吸附是吸热的、自发的，并且对骨炭具有很强的氟化物亲和力。氟化物解吸研究表明，氟化物从材料中解吸出 0.24% 至 20.06%，因此吸附被认为是部分可逆的。研究了骨炭在 400、500 和 600°C 下的再生，注意到其吸附能力略有下降，因此可以认为适合用于水处理技术。氟牙症和水中氟化物含量高的农村社区饮用井水中氟化物的吸附表明，通过增加 0.05 到 0.8 克的骨炭量，氟化物的处理量从 69.1% 增加到 98.7%。最后，确定从魔鬼鱼合成的骨炭是一种低成本、可行、
