Summary:•Shuttle/flower-like hydroxyapatie crystals have been synthesized under the combined action of sodium citrate and F127.•The morphology of the HAP particles evolved from nanoshuttles to hierarchical microflowers.•The HAP microflower exhibits fast adsorption ability for heavy metal ions. Shuttle/flower-like hydroxyapatie crystals have been fabricated by a simple hydrothermal treatment under the combined action of sodium citrate and a pluronic triblock copolymer (F127). The morphology characterization results demonstrate that the hierarchical flower-like hydroxyapatite microcrystals are evolved from the one-dimensional hydroxyapatie nanoshuttles. The effects of the additives and hydrothermal time on the morphology are studied. Based on the experiment results, this work presents a possible growth mechanism for the hydroxyapatite morphology. Remarkably, the adsorption experiments results exhibit that the HAP microflower have fast adsorption ability for heavy metal ions.
