Sunflower Waste Biomass as an Remarkable Adsorbent for Removal Heavy Metals from Aqueous Solution

Today through various industrial processes, toxic heavy metals released into aquatic environment that are harmful to all ecosystems. In the present investigation, removal of such contaminants from industrial waste waters is necessary. The purpose was made to extend an ecofriendly technology by using a bio carbon generated from sunflower wasted biomass.
The impact of initial pH of solution (2-10), initial heavy metal concentration and bio carbon dose on the adsorption processes was studied. Although determination of heavy metals done by atomic absorption spectroscopy, as the concentration of samples after adding adsorbent evaluate and capability of adsorbent has been defined.
The equilibrium data were found to be well described by Langmuire model. The langmuire is otherm feasibility was checked with the dimensionless separation factor (RL).
Introduction of new adsorbent represent a great challenge for both academia and industry. And along all methods for removal contamination, we choose adsorption processes. Overall, the work demonstrates the possible use of sunflower wasted biomass, as an effective adsorbent for removal of heavy metals from waste waters.
