Abstract
Textile Dye Removal by Activated Date Seeds
Highlights
Wastewater effluents are made up of toxic synthetic dyes which, when discharged into the environments, becomes a major concern due to esthetical and toxicological reasons [1]
Charcoal adsorbents sourced from agricultural wastes can achieve an acidic dye adsorption within 4 to 5 h in solutions with a pH range of 8-10 [2]
The X-ray diffractometer (XRD) patterns of the prepared activated carbon from date seeds (ADS) at different ADS concentrations were shown in Figures (3-5)
Summary
Wastewater effluents are made up of toxic synthetic dyes which, when discharged into the environments, becomes a major concern due to esthetical and toxicological reasons [1]. The adsorption equilibrium of a material (the ratio of the adsorbed amount to the residual amount in the solution) is determined when an adsorbate that contains a phase has been contacted with an adsorbent for a sufficient time, having its adsorbate concentration in the bulk solution in a dynamic balance with the interface concentration [5] Heavy metals such as lead, chromium, cadmium, and copper are mainly to produce the color pigments of textile dyes. The adsorption of different pollutants using agricultural waste products has been one of the economic and realistic approaches for wastewater decontamination from dyes and heavy metals before discharging into the environment [9]. Wastewater from the textile plants is a mixture of heavy metals, dyes, organic compounds, surfactants, total dissolved solids , salts, chlorinated compounds, biological oxygen demand, and chemical oxygen demand [10]
