biostudies-literatureUnknown19(20)Ashraf IFluoride contamination in water is a key problem facing the world, leading to health problems such as dental and skeletal fluorosis. So, we used low-cost multifunctional tea biochar (TBC) and magnetic tea biochar (MTBC) prepared by facile one-step pyrolysis of waste tea leaves. The TBC and MTBC were characterized by XRD, SEM, FTIR, and VSM. Both TBC and MTBC contain high carbon contents of 63.45 and 63.75%, respectively. The surface area of MTBC (115.65 m²/g) was higher than TBC (81.64 m²/g). The modified biochar MTBC was further used to remediate the fluoride-contaminated water. The fluoride adsorption testing was conducted using the batch method at 298, 308, and 318 K. The maximum fluoride removal efficiency (<i>E</i>%) using MTBC was 98% when the adsorbent dosage wInternational journal of environmental research and public health13092https://www.ebi.ac.uk/biostudies/studies/S-EPMC9603494biostudies-literatureNanoarchitectonics and Kinetics Insights into Fluoride Removal from Drinking Water Using Magnetic Tea Biochar.PMC9603494Elbeltagi AAltaf ARRizwan Aslam MAl-Ansari NLi RChen BAshraf IfalseNanoarchitectonics and Kinetics Insights into Fluoride Removal from Drinking Water Using Magnetic Tea Biochar.Fluoride contamination in water is a key problem facing the world, leading to health problems such as dental and skeletal fluorosis.
