We are living in a modern civilization with the help of a nuclear power facility. But, we are aware about the harmful effects of radionuclide's produced from nuclear power plants. So, the superiority in the technologies of nuclear waste treatment is prominent. Separation technologies are used to concentrate the radionuclides and prevent the spread of this hazard to the environment. This chapter has three parts: the first part discussed the types of membrane processes

“…In order to remove the heavy metal and radioactive metal pollution, many processes like adsorption (Aslani et al, 1998;Kilincarslan and Akyil, 2005), precipitation (Bhanushali et al, 1999), coagulation (Tresintsi et al, 2013), ion exchange (Akyil et al, 1996(Akyil et al, , 2003, cementation (Sun et al, 2014), electro-dialysis (Inoue et al, 2004), electro-winning (Liu et al, 2013), electro-coagulation (Verma et al, 2013), and reverse osmosis (Khedr, 2013) have been developed. Of these, the adsorption is one of the most effective methods used in the purification of heavy metal and radioactive metals from contaminated wastewaters.…”

Sandwich type polyelectrolyte nano-thin films (PENTFs) were prepared by using polyallylamine hydrochloride and polyacrylic acid from layer-by-layer assembly process with spin coating system. Their nanostructures have been studied by scanning electron microscope, atomic force microscope, and attenuated total reflectance Fourier transform infrared spectroscopy. In order to understand the effects of the initial concentration of thorium, initial solution pH, temperature, and contact time on the reaction between thorium and PENTF, an experiment data set was designed according to Box-Behnken model. The analysis of variance calculations for regression model were carried out in 95% confidence level and were checked for fitting experimental data and predicted values. The correlation coefficient value (R 2) obtained as 94% showed that there was a correlation between the predicted and the observed values. The optimum pH, temperature, initial concentration of thorium, and interaction time in studied ranges were found as 2.81, 35 C, 160 mgÁL À1 , and 120 min, respectively. At these conditions thorium (IV) ions adsorption yield was obtained as 89 AE 2%. The Freundlich, Langmuir, and Dubinin-Radushkevich isotherms were used to investigate the characteristics of the process. These characteristics data imply that the Freundlich model fits better than the Langmuir model for the Th (IV) sorption onto PENTFs with K F and n values were found to be 20.6 mgÁg À1 and 1.08 LÁmg À1 , respectively. The thermodynamic parameters were also computed as negative ÁH value suggest that adsorption of Th (IV) is exothermic nature. The calculated negative and positive values of ÁG indicate that the sorption process is favorable (energetically) while running below 40 C and over this point the process status change to non-spontaneous, respectively.
