The sorption capacity of the BHAP for both Sr and Co was higher than for a synthetically produced hydroxyapatite (HAP) in the solutions tested. Results confirm that hydroxyapatite minerals of high surface area and amorphous calcium phosphate content, typical for biogenic sources, are suitable restoration or reactive barrier materials for the remediation of complex contaminated environments or wastewaters.
