花状多孔Fe3O4纳米材料对水中氟离子吸附性能的影响
Effect of flower-like porous Fe3O4 nanomaterials on adsorption performance of fluoride ion in water
摘要
Abstract
This paper aims to mitigate the health risks and environmental hazards caused by fluoride-contaminated water.By using the hydroxide precursors method of a simple and mild thermal treatment for iron,the study involves preparing flower-like porous Fe3O4 nanomaterials as an adsorbent for fluoride re-moval,and systematically investigating the effects of system pH,initial fluoride concentration,and adsor-bent dosage on adsorption performance of fluoride ion.The results show that the Fe3O4 nanomaterial at pH is approximately 3 with a dosage of 1 g/L,offers better adsorption and removal rate to the fluoride ion in water with a maximum adsorption capacity of 24.24 mg/g,and an 82.96％removal rate of fluoride ion(5 mg/L).The adsorption process conforms to both the Langmuir isotherm model and pseudo-sec-ond-order kinetic model,falling into monolayer chemical adsorption.This material could be collected and recycled effectively.关键词
