Adsorption of Ni(II) Ion from Industrial Effluents Using a Low-Cost Adsorbent: Kinetic and Optimization Studies

Nowadays water pollution raises a great attention since water constitutes a basic necessity in life and it is very essential to all living things. The aim of the present work was to analyse the removal of toxic metal Ni(II) in using available natural adsorbents, namely TectonaGrandis activated carbons. This study was carried out to examine the adsorption capacity of the low-cost adsorbent for the removal of heavy metal, Ni(II) from the industrial effluents. The influence of initial concentration, contact time, pH, adsorbent dose and temperature on the adsorption process also studied. Results revealed that the adsorption isotherms could be fitted well by the Langmuir model. The RL values in the present investigation was less than one, indicating the adsorption of Ni(II) ion is favourable in the above adsorbents. Results indicate the freely abundant, locally available, low-cost adsorbent, TectonaGrandisactivated carbons can be treated as economically viable for the treatment of metal ion from the industrial effluents.
