Adsorption is one of the efficient cost-effective separation processes that is in use for the removal of water and gaseous pollutants. This book provides a balanced mix of fundamental adsorption theory and application with a compilation of up-to-date developments and trends. It presents fundamental and advanced knowledge on solid/liquid and gas/solid separation unit operations and critically discusses the reaction-based mechanism of adsorption and adsorptive parameters estimation.
Key Features:
- Puts emphasis on adsorption for water and gas remediation, reviewing state-of-the-art of the technology as well as introducing beginners to adsorption
- Explores factors affecting the adsorption separation process including types of adsorbents and composite nano-adsorbents
- Includes batch and continuous unit operation and design calculations
- Proposes development of a sustainable cost-effective water filter including arsenic rich water purification
- Discusses utilization of industrial and agricultural solid waste in alternative adsorbents during solid/liquid and gas/solid separation
This book is useful for researchers and graduate students in chemical and environmental engineering and analytical chemistry.
