Fluoride Sorption Using Zirconium ion-impregnated Macadamia Nutshell-Derived Biochar from Aqueous Solution: Adsorption Isotherms and Kinetic Modeling

Yegon, Andrew; Mtavangu, Stanslaus; Rwiza, Mwemezi; Machunda, Revocatus (Research Article, 2022-11-26)

Zirconium ion-impregnated macadamia nutshell biochar (ZMNB) was synthesized and tested for its fluoride sorption capacity by exploiting batch experiments. Four temperatures (300, 400, 500, and 600 ℃) were used to pyrolyze ...
Optimization, Characterization and Modeling of Functionalized Macadamia Nutshell Derived-Biochar for Drinking Water Defluoridation

Yegon, Andrew; Mtavangu, Stanslaus; Rwiza, Mwemezi; Machunda, Revocatus (Springer International Publishing, 2025)

Fluoride contamination in drinking water is a serious global environmental concern owing to its irreversible health effects. This study synthesized Zr(IV)-impregnated macadamia nutshell biochar (Zr-MNSB) by the surface ...
