Efficient immobilization of Cd2+ by nanoscale carbonate hydroxyapatite synthesized by ureolytic bacteria

As one of the five most toxic heavy metals, cadmium pollution seriously endangers human health and food safety. Carbonate hydroxyapatite has attracted our attention because of its excellent cleaning ability. However, few ecofriendly synthetic processes of nanoscale carbonate hydroxyapatite limit its application. In this study, we designed a medium that was used to prepare carbonate hydroxyapatite through microbial mineralization. The nano-flaky...
