Description
Present work illustrates the removal of copper ion (i.e. Cu2+) from water using hydroxyapatite (HAp) adsorbent. HAp powder was synthesized by chemical precipitation method. The developed HAp powders were characterized through FESEM images alongside the EDX analysis confirming the presence of calcium and phosphorous elements. Batch adsorption experiments were conducted mainly using HAP. The copper (II) ion adsorbed HAp was also characterized using, FESEM and EDX analysis. On the basis of the adsorption experimental results a treatment unit/set up has been developed for the purpose of removal of copper from water. The adsorption candle was made by mixing HAP and activated charcoal in a certain proportion. Activated charcoal was used mainly to increase the flow rate of water through the adsorbent candle. Prototypes were developed to investigate the initial copper ion concentration of 3mg/L and 6mg/L. The prototypes thus developed have proven to be successful as more than 1000 litres of copper contaminated water has been treated whilst maintaining the effluent copper concentration well below the permissible limit.
