Abstract
Inorganic arsenic ions such as As3 + in the environment have become one of the potential risks for human health. In this work, 3D flower-like hydroxyapatite agglomerates were converted from natural egg-shell powder under mild conditions and applied on the detection of As3 +. The effect of conversion time on the determination capability was investigated. This biomaterial has been demonstrated to be highly sensitive to trace As3 + with a limit of detection down to 0.034 ppb.
► A low-cost way for fabricating 3D flower-like hydroxyapatite has been proposed. ► This biomaterial can be used for highly sensitive detection of As3+. ► The LOD is down to 0.034 ppb, much lower than previously reported electrodes.
