Figure 7: Reusability study of up to six times for the removal assay of [1.6 x 10-3 M] p-Cl-Ar-NH2 onto [10 g/L] hexagonal and cubic Fm3maluminosilica adsorbents fabricated with a Si/Al ratio of 1 at 40 °C. Note that the efficiency (E) was calculated from the % ratio of the uptake (%U) per reuse cycle (No.) and the initial uptake obtained from the initial use of the adsorbents.
