Comparative study of Pb2+, Ni2+, and methylene blue adsorption on spherical waste solid-based geopolymer adsorbents enhanced with carbon nanotubes

Shu Yan et al.

Summary: Spherical porous carbon nanotube-reinforced geopolymer (CNTs/GP) adsorbents were prepared by combining carbon nanotubes (CNTs) with a fly ash and slag-based geopolymer slurry and spheroidizing in poly-ethylene glycol 400 solvent. The CNTs/GP spheres exhibited a perfect spherical shape, mesoporous structure, and enhanced adsorption efficiency for methylene blue (MB) and heavy metals (Pb2+ and Ni2+). The adsorption data of the spheres followed Langmuir isotherm and pseudo-second-order kinetics models, suggesting multiple mechanisms were involved. The CNTs/GP spheres also exhibited good cyclic regeneration properties, making them promising adsorbents for hazardous wastewater treatment.

Development of porous and reusable geopolymer adsorbents for dye wastewater treatment

Chan Juan Li et al.

Summary: In this paper, a cost-effective hierarchical pore geopolymer based on solid waste was synthesized and showed excellent adsorption properties for removing methylene blue dye from wastewater. The acid-treated geopolymer particles exhibited a high specific surface area and microporosity, providing abundant adsorption sites for the dye. The optimal geopolymer adsorbent achieved a high adsorption efficiency and removal efficiency, and showed good regeneration performance and selectivity towards cationic dyes.

3D printed geopolymer adsorption sieve for removal of methylene blue and adsorption mechanism

Haize Jin et al.

Summary: Geopolymers are highly promising materials with exceptional ion exchange ability. Through the investigation of a novel direct ink writing (DIW) geopolymer adsorption sieve (GAS) preparation strategy and its adsorption properties and mechanism for methylene blue (MB), it was found that GAS exhibited desirable adsorption rates and characteristics. Furthermore, the adsorption process was influenced by electrostatic action, hydrogen bonds, and electron transfer.

A review on the utilization of red mud for the production of geopolymer and alkali activated concrete

Aman Kumar et al.

Summary: The production of ordinary Portland cement has harmful effects on the environment, leading to the utilization of industrial waste products to synthesize geopolymer materials and alkali-activated binders as an alternative. Red Mud, a harmful radioactive waste material, can be used in the synthesis of these materials, providing better environmental stability.

Rapid removal of methylene blue and nickel ions and adsorption/desorption mechanism based on geopolymer adsorbent

Haize Jin et al.

Summary: The research focused on improving the adsorption efficiency of geopolymer as an adsorbent for heavy metal ions and dyes removal. The adjustment of pH enhanced the rapid removal of methylene blue and nickel ions by exposing more negative charge adsorption sites. Additionally, the study found that the desorption of nickel ions was facilitated by a decrease in pH of the wash solution.

Simple Model for Alkali Leaching from Geopolymers: Effects of Raw Materials and Acetic Acid Concentration on Apparent Diffusion Coefficient

Neven Ukrainczyk

Summary: This study investigated alkali leaching from geopolymers in different concentrations of acetic acid solutions, proposing a new method for acid attack. The results showed that the chemistry of alkali release from the gel mainly governed the apparent diffusion coefficient of geopolymers, with distinct differences in D-app attributed to variations in mix designs.

Printing Parameter Requirements for 3D Printable Geopolymer Materials Prepared from Industrial Side Streams

Qaisar Munir et al.

Summary: This investigation focused on studying the printing parameter requirements for sustainable 3D printable geopolymer materials using side streams of industries as raw materials. Results showed that heating significantly improved buildability and setting of the material, while an increase in reactive recyclable material content led to decreased strength and workability. Furthermore, longer curing time increased compressive strength but decreased flexural strength, and the number of layers in test samples affected their strength performance.
