Arsenic(As) contained in drinking water can cause adverse effects on human health. This study investigated the effect of hydroxyapatite nanoparticles (nano-HAp) on sorption of As(V) ions in aqueous solution. The amounts of arsenic ion,nano-HAp and pH on removal efficiency were also investigated. Results showed that the removal of arsenate from water using hydroxyapatite nanoparticles, improved with increasing pH. The optimum amount of nano-HAp for As (V) removal is found to be 0/6 g/L with the removal efficiency of 88 %. The sorption data were then correlated with the Langmuir, Freundlich, adsorption isotherm models. The results indicated that nano-HAp can be used as an effective adsorbent for removal of As(V) from aqueous solution.
