This study investigated the defluoridation efficiency of hydroxyapatite-activated seaweed (<em>Eucheuma Cottonii</em>) biochar (HSB) at various soil pH ranges (3&ndash;11) while monitoring the impact of contact time (30 min - 2.5 h), adsorbent dosage (0.1&ndash;0.5 g) as well as the initial fluoride concentration and compare its performance to its respective seaweed biochar (SB). Activation of SB with the hydroxyapatite lead to a shift in its point-zero-charge (pHPZC) from 6 to 7.4 broadening its defluoridation pH range from a solitary 5 to amid 3 through 11.
