7, the maximum removal of Cr(VI) by CATCS was at pH = 5, which implied the CATCS flocculant trended to adsorb Cr(VI) in form of HCr[O.
e] (mg/g) is the amount of Cr(VI) adsorbed on per unit weight of CATCS, [C.
It was evident from these data that the surface of CATCS was made up of homogeneous and heterogeneous adsorption patches.
The negative [DELTA]G implied the process of Cr(VI) removal by CATCS was spontaneous.
The kinetic curves of Cr(VI) removal by CATCS at various temperatures are shown in Fig.
e] (mg/g) are the amounts of Cr(VI) adsorbed onto the CATCS at time t and equilibrium, [k.
The kinetic parameters for Cr(VI) adsorbed onto the CATCS were summarized in Table 4 and the fitting plots of pseudo-first order kinetic model and pseudo-second order equation were shown in Figs.
The activation energy of Cr(VI) absorbed onto CATCS was determined using the Arrhenius equation [49] Eq.
a]) of the adsorption process of Cr(VI) by CATCS was 29.
