In the present work treated dhoopbatti (incense stick) ash (TDA) is used as an adsorbent for the removal of copper from its aqueous solution. The adsorbent is a waste material left after worship of Hindu God; it is easily available in Hindu temples. The effect of contact time, initial concentration, adsorbent dose and pH were studied on the removal percentage of metal ions. The TDA is first time used as adsorbent and found to have good adsorption properties. Cu(II) adsorption was maximum at pH 3 and it was also observed that as the pH increases, the adsorption began to decrease. It was observed during study that removal of copper decreases with increase in initial concentration. The SEM image and FTIR spectra of TDA clearly shows that various functional groups are attached in TDA which enhances the adsorption capacity of adsorbent. The Langmuir isotherm was also applied during present study which shows monolayer adsorption.
