| Abstract | ||||
| The leather industry has a high economic return, but also has harmful effects on society and the environment. One of the most important of these harmful effects is the problem of salinity of water bodies, soil and groundwater. The main objective of the research is to improve the quality of industrial effluent for safe use in agricultural purposes. Green tea (GT), pomegranate peels (PP) and potato peels (Po) were washed with hot distilled water at 85°C several times until its color fades and dried in oven at 105°C and then burned at 400°C, the dried wastes were chemically activated with 1.0 M sulphuric acid for three hours and washed several times with distilled water and dried again. The obtained carbon was ground to very fine powder and characterization by transmission electron microscopy. Nanoparticles size of green tea spoil carbon(GTCn), pomegranate peels carbon (PPCn) and potato peels carbon (PoCn) ranged between 1-50 nm. The result indicated that the effect of green tea spoil carbon nanoparticles at three layers (GTCn3) in addition to potato peels carbon nanoparticles at one layer (PoCn) on removal of salinity from tannery effluent was 99.85% and the parameters of EC, TDS, soluble cations and anions were less than permissible limits for discharge into water bodies. The agricultural residues carbon nanoparticles adsorb the hateful odor, remove yellow color and remove the turbidity. | ||||
