Table 3 lists the comparison of the adsorption capacity of TCF
with that of nanoparticles previously investigated. It can be seen
that the adsorption capacity of TCF was not less than that of activated
carbon, chitosan, and other adsorbent nanomaterials. This
suggested that the TCF adsorbent we prepared can be considered as
a promising adsorbent for Cr(VI) removal from wastewater.
