Adsorption–desorption of heavy metal ions
Adsorption and desorption studies on different types of adsorbents, including natural materials such as teak tree bark powder, rice husk, natural bentonite, different algae like Ecklonia maxima, Escherichia coli, Ascophyllum nodasum, Rhizopus nigricans, Cladophora fascicularis, goethite and soils of three nuclear power plant and artificial materials such as Fe oxide-coated sand, goethite pretre...
متن کاملHeavy metal adsorption by clinoptilolite from aqueous solutions
The present investigation has been carried out to assess a chromium, cobalt, and cadmium from wastewaters by natural and modified zeolites were examined by using batch type method. A clinoptilolite type synthetic / natural zeolite were pretreated with HCl and HNO3 to improve the adsorption capacity for heavy metals. The removal efficiencies and kinetics of heavy metals such as chromium, cobalt ...
متن کاملUsing Nanocomposites of Chitosan and Montmorillonite for Adsorption of Heavy Metal Ions from Wastewater
Common technologies for heavy metal removal are membrane separation, ion exchange, electro-deposition, and chemical precipitation. These methods prove to be costly and inept, especially in removing trace amounts of heavy metals [2]. Another disadvantage is the production of sludge or mud, which requires proper disposal and confi nement [3]. On the other hand, adsorption eff ectively removes con...

متن کاملRemoval of heavy metal from industrial wastewater using chitosan coated oil palm shell charcoal
* Corresponding author This research focuses on understanding biosorption process and developing a cost effective technology for treatment of heavy metals-contaminated industrial wastewater. A new composite biosorbent has been prepared by coating chitosan onto acid treated oil palm shell charcoal (AOPSC). Chitosan loading on the AOPSC support is about 21% by weight. The shape of the adsorbent i...
