1]H-NMR spectrum of DTOF copolymer and SDTOF terpolymer resins is depicted in Fig.
Figure 3a and b shows structural changes for DTOF resin before and after nickel loading, respectively.
Therefore, the sorption capacity of the DTOF copolymer and SDTOF terpolymer resins were performed at different pH levels in the range of 1.
The effect of agitation period on the adsorption of Ni(II) onto DTOF copolymer and SDTOF terpolymer resins is depicted in Fig.
Figure 6 shows the effect of DTOF and SDTOF resins concentration (g [L.
e] is the amount of nickel adsorbed per unit weight of the DTOF and SDTOF resins (mg [g.
2]), it is possible to suggest the best isotherm model to explain the adsorption of Ni(II) onto DTOF and SDTOF resins.
In order to investigate the adsorption of Ni(II) ions onto DTOF and SDTOF resins, the following kinetic models are generally used to test experimental data.
From these results, it can be concluded that the pseudosecond-order kinetic equation provided the best model for describing the adsorption of the nickel onto DTOF and SDTOF polymer resins.
From this curve, the adsorption capacities of DTOF and SDTOF resins were found to be 94.
3], and EDTA were used for the elution of previously adsorbed Ni(Il) onto DTOF copolymer and SDTOF terpolymer resins.
1 g of DTOF and SDTOF resins was achieved by desorbing the adsorbed nickel (II) and this was done by using 0.
