The remediation of heavy metal-contaminated soils has attracted increased attention
worldwide. The immobilization of metals to prevent their uptake by plants is an efficient way
to remediate contaminated soils. This work aimed to seek the immobilization of cadmium in
contaminated soils via a combination method. Flask experiments were performed to
investigate the effects of hydroxyapatite (HAP) and the Cupriavidus sp. strain ZSK on soil pH
and DTPA-extractable cadmium. Pot experiments were carried out to study the effects of the …
