Abstract
removal of toxic heavy metals ions, such as aluminum (III) and Zinc (II) and Nickel (II) from wastewater using the activated carbon of both apricot stone and guava leaves.
The thesis is divided into three major chapters, introduction, experimental and results and discussions. Also the thesis contain references, Arabic and English summary and aim of the present work.
1. The first chapter represents the definition of pollution, pollution with heavy metals ions, toxicity of aluminum (III) and Zinc (II) and Nickel (II) and methods used for removal of these heavy metals ions as well as literature survey on the previous work.
2. The second chapter deals with the experimental part, the method used for the removal of aluminum (III) and Zinc (II) and Nickel (II) and the instruments used for the adsorption processes.
3. The third chapter deals with the results and discussion and application.
Removal of aluminum (III) and Zinc (II) and Nickel (II) ions from waste water by adsorption.
It included the results of the ability of selected adsorbents such as using activated carbon of both apricot stone and guava leaves to remove aluminum (III) and Zinc (II) and Nickel (II) ions from wastewater at different conditions as contact time, amount of adsorbent, temperature, initial concentration and pHs. In order to find out thermodynamic and kinetic parameters, equilibrium adsorption models were applied. Although experimental data was confirmed with both Langmuir and Freundlich isotherm models, Adsorption rate constant was determined from Lagergren equation and pseudo-second order equations and inter particular diffusion equation.
It is found that, the adsorption was dependent on contact time, initial aluminum (III) and Zinc (II) and Nickel (II) ions concentration, adsorbent dosage, magnetic stirrer speed, volume of solution and temperature. The sorption of aluminum (III) and Zinc (II) and Nickel (II) ions onto activated carbon of both apricot stone and guava leaves is strongly dependent on pH value. The
