Abstract
Adsorption is an effective method for water and wastewater treatments. The adsorption process is widely used to remove dyes from colored wastewater due to its easy application and simple design. In addition the interesting aspect of adsorption is due to the transfer of target substances from solutions onto adsorbent surfaces. Traditional adsorbent materials suffer from some disadvantages such as poor separation ability and relatively limited adsorption capacity for dyes. Thus researchers have found interest in new adsorbents. In this paper, dye removal ability of zinc-nickel ferrite nanoparticle type of material as a magnetic adsorbent was studied. Basic Blue 41 (BB41) and Basic Red 18 (BR18) were used as model dyes. Uv-vis spectrophotometer was used to follow and record the dye removal. The effect of adsorbent dosage and dye concentration on dye removal was studied. Direct dyes were removed from wastewater. Adsorption isotherm followed the Langmuir isotherm and the adsorption kinetics followed pseudo-second order. The results showed that zinc-nickel ferrite nanoparticle can be used as an effective magnetic adsorbent to treat colored wastewater.
