Sahu Jain college Najibabad, Distt-Bijnor 246763 (UP) (India) <p>The present paper reveals that the potential of China clay and Fly ash were used as adsorbent for the removal of heavy metals such as Ni(II) and Mo(VI) from known concentration of waste water was investigated. Hence the study indicates that the low cost adsorbent of China clay is used for removing 90% and 69% of Ni(II) and Mo(VI) respectively. Fly ash used for removing 84% and 77.6% of Ni(II) and Mo(VI) from wastewater from the initial metal ion concentration of 4.26x105 M and 1.49x105M solution respectively. Batch adsorption studies demonstrated that the adsorbents had significant capacity to adsorb Ni(II) and Mo(VI) from aqueous solution. It was found that the adsorption increased with increase in contact time. Also, percentage adsorption depends on change in pH of N(II) and Mo(VI) solution.</p> https://ultraphysicalsciences.org/paper/1530/ Heavy metals Adsorbents, Effect of Contact time Agricultural waste
