Tiivistelmä
Porous alkali-activated materials (AAMs) are known to be sustainable and cost-effective alternatives for conventional adsorbents in wastewater treatment. These materials offer environmentally friendly synthesis routes accompanied with high adsorption capacity and efficiency. As demonstrated through a review of existing literature, this study investigates the effect of the geometric shapes of porous AAMs in the efficiency of wastewater treatment.
The study discusses the influence of geometric shapes, including spheres, cubes, and cylinders, on adsorption kinetics and capacity of the AAMs. Additionally, this work explores the structural characteristics, synthesis methods and adsorption mechanisms of porous AAMs. Adsorption experiments conducted using batch and column adsorption modes were reviewed. Batch adsorption studies were analyzed using Langmuir, Freundlich, and Sips isotherm models, while column adsorption behavior was evaluated through Thomas and Yoon-Nelson models to assess breakthrough curves.
Findings from the literature survey indicates the capability of application of different geometric shapes of porous AAMs as versatile and scalable adsorbents, capable of effectively removing pollutants such as heavy metals and dyes and other pollutants from wastewater. Furthermore, this work provides valuable insights into the relationship between material composition, structural geometry, and adsorption mechanisms of porous AAMs.
