Elimination of Heavy Metals from Wastewater Using Agricultural Wastes as Adsorbents
The adsorption process is being widely used by various researchers for the removal of heavy metals from waste streams and activated carbon has been frequently used as an adsorbent. Despite its extensive use in the water and wastewater treatment industries, activated carbon remains an expensive material. In recent years, the need for safe and economical methods for the elimination of heavy metal...
متن کاملRemoval of heavy metals from waste water using different biosorbents
The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...
متن کاملAdsorption Study of Heavy Metals Removal from Wastewater Using PVA- Nano Ferrite Composites
The aim of the present investigation is to synthesize Barium ferrite and Nickel ferrite Nanoparticles by co-precipitation method and these nanoparticles are used to prepare nanocomposites with poly vinyl alcohol (PVA). The composited nanoparticles are characterized by using FTIR, XRD and SEM. The synthesized nanoparticles are used as adsorbent to remove the heavy metals such as Cu2+...
متن کاملCommercial Coffee Wastes as Materials for Adsorption of Heavy Metals from Aqueous Solutions
This work aims to study the removal of Cu(II) and Cr(VI) from aqueous solutions with commercial coffee wastes. Materials with no further treatment such as coffee residues from café may act as adsorbents for the removal of Cu(II) and Cr(VI). Equilibrium data were successfully fitted to the Langmuir, Freundlich and Langmuir-Freundlich model (L-F). The maximum adsorption capacity of the coffee res...
متن کاملRemoval of Heavy Metals from Wastewater Using Cow Bone Charcoal
Bone charcoal, a mixed adsorbent containing around 10% carbon and 90% calcium phosphate, is mainly produced by thermal treatment of bones. Structurally, calcium phosphate in bone charcoal is in the hydroxyapatite form [1-2]. Traditionally, bone charcoal has been used to remove color in sugar solutions in the sugar refining industry. Recent studies use bone charcoal to adsorb radioisotopes of an...
