As shown by Fig. 10, at HNT loading fraction of 25% and 50 wt%,the adsorption capacity of the beads comprising the HNTs minedfrom Dragonite had a larger adsorption capacity of 14.2 mg/g ascompared to that of Matauri Bay, 10.55 mg/g. The difference inadsorption capacity could be due to the difference in the struc-ture of the HNT used. As shown in Table 2, the surface area
