Abstract:The application of chitosan-based materials for the separation
of uranium from wastewater was limited due to the lack of active sites.
In this work, a chitosan-based composite (CaCO3@aCS/PA)
was effectively created by modifying chitosan with CaCO3 and phytic acid to enhance the adsorption performance of chitosan
materials. CaCO3@aCS/PA showed no significant changes and
no Ca2+ was detected in the solution after stirring for
10 h in a solution with pH > 3, indicating good stability of CaCO3@aCS/PA, which was be… Show more
