Effects of Acid Treatment on the SEM-EDX Characteristics of Kaolin Clay [PDF]

open access: yes, 2017
Raw kaolin was refluxed by sulphuric acid in variable concentrations of 2 M, 4 M, 6 M and 8 M. The morphology and elemental compositions of the acid-leached kaolin were analyse by Field Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray ...

Ligand‐Engineered Mesoporous Silica: Cutting‐Edge Architectures for Targeted Toxic Heavy Metal Sequestration—A Review

open access: yesAdvances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The mesoporous silica (MPS) modified with organic ligands has been effectively employed since last decade as a nonconventional, highly efficient, and selective adsorbent for the removing of heavy metal ions (HMIs) from their aqueous media. Therefore, this research paper is focused on reviewing various research works carried out on the use of ligand ...
