Removal of Reactive Yellow -145 Dye from Simulated Industrial Waste Waters Over Iraqi Deegle Date Palm Seeds Based Activated Carbons

The current study describes synthesis of new type of activated carbon (AC) from Iraqi deegle date palm seeds (IDDPS). This type of AC was synthesized using chemical activation method with using ZnCl2 as a chemical activator. The activity of this material as adsorbent was performed via following removal of reactive yellow dye 145 (RYD145) from simulated industrial wastewater. The synthesized AC was investigated using scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) Different physical properties were undertaken such as ash content, adsorption uptake capacity, humidity, point zero charges of the AC were calculated. Removal of this dye was considered to be as a model of the polluted dyes from textile industries and it was treated using batch tests. Removal of this dye in this work was performed applying different reaction parameters and conditions. This including amount of the used AC for each batch, effect of pH on dye removal a, effect of temperature, and duration of time on the adsorption process. The activity of the synthesized AC on dye removal was compared with the non- activated carbon (NAC) that is synthesized from IDDPS. The obtained results showed that AC was more efficient in dye removal in comparison with NAC under the same conditions.
