纳米羟基磷灰石纳米管的一种简便制备方法及其对溶 液中重金属离子的吸附（英文） Title:ASimplePreparationMethodofHydroxyapatite NanotubesandTheirAdsorptionofHeavyMetalIonsinSolution Abstract: Hydroxyapatite(HA)nanotubeshavegainedsignificant attentionduetotheiruniquestructuralandfunctionalproperties. Inthisstudy,asimplepreparationmethodforhydroxyapatite nanotubeswasdeveloped,andtheiradsorptioncapacityforheavy metalionsinsolutionwasinvestigated.Theprepared hydroxyapatitenanotubesexhibitedhighadsorptioncapacityand selectivityforheavymetalions,makingthemapromisingmaterial forvariousenvironmentalremediationapplications. 1.Introduction 1.1Background Heavymetalions,suchaslead,cadmium,andmercury,are toxicpollutantsthatposeseriousthreatstohumanhealthandthe environment.Variousmethodshavebeendevelopedtoremove heavymetalionsfromcontaminatedsolutions,includingchemical precipitation,ionexchange,andmembranefiltration.However, thesemethodsoftensufferfromlimitationssuchashighcost,low efficiency,andsecondarypollution.Therefore,noveladsorption materialswithhighadsorptioncapacityandselectivityare urgentlyneeded. 1.2Significance Hydroxyapatitenanotubeshaveshowngreatpotentialfor efficientadsorptionofheavymetalionsduetotheirunique structureandfunctionalproperties.However,thereisaneedto developasimpleandscalablemethodforthepreparationof hydroxyapatitenanotubes,aswellasinvestigatetheiradsorption capacityforheavymetalionsinsolution. 2.MaterialsandMethods 2.1Materials
