Carbon quantum dots (CQDs) are the new generation of nanoparticles that have attracted interest for their utilization as modifiers. In this study, a composite of metakaolin(MK)/CQDs was synthesized and tested for methylene blue (MB) removal. The heating and acid-alkali treatment of kaolin transformed it into MK. The interaction between MK and CQDs was analyzed using XPS to detect the binding of pyridic NH2 and C-N. By loading CQDs into the kaolin matrix, the surface area was improved and the removal of MB increased. For a lower MB concentration at 5 ppm, the removal efficiency could reach 96. The composite exhibited good regeneration through the recyclability test. © 2022 Tim Pengembang Jurnal UPI. date: 2022 publisher: Universitas Pendidikan Indonesia official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85138559567&doi=10.17509%2fijost.v7i2.50810&partnerID=40&md5=c3c13588990185af8f64a9c6f5733ab3 id_number: 10.17509/ijost.v7i2.50810 full_text_status: none publication: Indonesian Journal of Science and Technology volume: 7 number: 2 pagerange: 311-336 refereed: TRUE issn: 25281410 citation: Sambudi, N.S. and Sithambaran, Y. and Hui, K.C. and Nugraha, M.W. and Kamal, N.A. and Harun, N.Y. and Sufian, S.
