Fluoride removal by modified biochar

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Catalog Last Checked: April 21, 2026 at 07:59 PM | Dataset Last Updated: March 17, 2020
This data set includes physicochemical properties of douglas fir biochar (DF-BC), dairy manure biochar (DM500) and calcium modified dairy manure biochar (Ca-DM500) such as SEM images and EDS analysis of the Ca-DM500 and surface area analysis (BET) of all three biochars. The data set also includes: Physiochemical properties and characteristics of the biochars A) DRIFTS analysis, B) Point of zero charge, C) Particle size, D) pH, and E) X-ray diffraction. Batch tests to investigate fluoride removal behavior including initial screening tests, pH effects, isotherms, kinetics co-existing ion competition and continuous flow columns. Isotherm data were modeled using Langmuir, Freundlich and Redlich-Peterson Models. Column data were modeled using the Thomas model (Thomas 1944). This dataset is associated with the following publication: Wallace, A.R., C. Su, Y. Choi, E. Kan, and W. Sun. Removal of Fluoride from Water Using a Calcium-Modified Dairy Manure-Derived Biochar. JOURNAL OF ENVIRONMENTAL ENGINEERING. American Society of Civil Engineers (ASCE), Reston, VA, USA, 146(12): 1-10, (2020).
