Removal of Cd(II) and Ni(II) from Contaminated Waters Using Nano Particles Bagasse Fly Ash
Existence of healthy water sources without poisonous and dangerous pollutant is a significant requirement for a healthy and sustainable society. It is well known that heavy metals such as cadmium and nickel in environment are a serious threat to plants, animals and human because of their bioaccumula...

Existence of healthy water sources without poisonous and dangerous pollutant is a significant requirement for a healthy and sustainable society. It is well known that heavy metals such as cadmium and nickel in environment are a serious threat to plants, animals and human because of their bioaccumulation, nonbiodegradable property and toxicity even at low concentrations. This metals were entered from industrial wastes consume oil, urban waste water to environment. in this study, nano particle bagasse fly ash was used to removal of Cd(II) and Ni(II) from contaminated waters by batch adsorption experiments. First experiments related to pH were carried out on aqueous solution at the concentration 5 ppm, amount of adsorbent 10 g/L, contact time 12 hours with pH of the solution varying from 3 to 8.
