Spectrophotometric Determination of Cd (II) Heavy Metal by Using Stone Apple Shell as a Low Cost Adsorbent

The toxic element Cadmium (II) was determined by using the widely and easily available shells of fruits of stone apple with a good result. The cadmium is a highly toxic element in a trace amount also, therefore its detection is most important. In the present work the effective and powerful adsorbent properties of shells of waste fruits of stone apple (Aegle marmelos) were thoroughly studied. In this work the determination of Cadmium (II) heavy metals from the solutions of its salt were efficiently carried out. The efficiency of removal of Cd (II) was found to be 85 % at the optimum pH 6.7 and the contact time was 118 min for the toxic metal Cadmium (II). The adsorbent used in the present work was ecofriendly cost effective and easily available and will become the better substitute adsorbent for the removal of heavy metal Cd (II). The different parameters such as contact time, effect of pH, initial concentration of metal ions and amount of adsorbent on the adsorption capacity were studied by using the double beam UV-Visible Spectrophotometer.
