| Abstract Scope |
Clay is commonly used to remove pollutants like heavy metals from water. It has excellent properties, such as high cation exchange capacity and a large specific surface area. Various techniques can be used to improve these materials, including organic modification using polymers, calcination, acid activation, and modification through surfactant adsorption. This research aims to discuss recent findings on enhancing clay minerals through surfactant modification. Following X-ray diffraction analysis (XRD), the shift of basal spacing (001) value of clays from 14.83 to 19.63 Å, or 7.12 to 7.34 Å indicating the successful alteration of clays by surfactant, while From the FTIR spectrum of surfactant-modified clay, the appearance of new vibration bands between 2850 and 2926 cm-1, corresponding to the asymmetric and symmetric vibration of the CH which indicates the successful interaction of surfactants onto clay interlayer. The Brunauer-Emmett-Teller analysis revealed that the interaction of the surfactant with the clay increases the interlayer spacing, resulting in a larger pore diameter. These results indicate structural changes in the clay after modification. The findings suggest that surfactant-modified clays have improved adsorption properties, making them suitable for environmental applications. |
