Extraction of Cobalt From Synthetic Waste Water Using Low Cost Adsorbent (Delonix Regia)

Cobalt is beneficial for humans because it is in Vitamin B-12 but its high concentration may cause health problems like heart problems, thyroid damage etc. The present work focused on the effectiveness of low cost adsorbent (Gulmohar kernel powder) for the removal of cobalt (II) from synthetic Waste water investigated by column process. FTIR results indicated the presence of number of active sites present on the adsorbent as compared to Activated Carbon. UV Visible spectroscopy results shows maximum adsorption capacities of Co(II) 72.22% from synthetic water. It is reused in the synthesis of complex and practical % yield of regenerated cobalt obtained is 56.46%.
