AlCrO3-grafted g-C3N4 composite for cadmium ions removal: A paradigm shift in environmental remediation
The appealing graphitic phase carbon nitride (g-C3N4) is extensively utilized for environmental remediation; however, some of its intrinsic drawbacks still need to be amended. Herein, the g-C3N4 quality was improved by anchoring to AlCrO3 nanoparticles to acquire a competent ternary AlCrO3@g-C3N4 composite for the cadmium ions elimination. The composite elemental compositions were verified by the EDX and XPS to specify the C, N, Cr, Al, and O as the composing elements, and the XRD structural analysis revealed the development of both the g-C3N4 and AlCrO3. The presence of some functional groups (C–N, CN, –NH–, –NH2, and –OH) as detected by the FTIR and a large surface area of 89.94 m2 g−1 qualified it to successfully eliminate.mg.g−1 of Cd+2 ions from an aqueous solution. The Cd+2 ion adsorption was found to follow the Langmuir isotherm model, while the kinetics matched with the pseudo-second-order style. The high adsorption aptitude of the synthesized adsorbent could be accredited to the numerous adsorption sites, π-π conjugate interactions, and electrostatic attractions with the metal ions in water as publicized by mechanistic study.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
