Characterization of three Pb-resistant fungi and their potential Pb2+ ions adsorption capacities

Total antioxidant capacities and reduction of ferric ions by extracts of three medicinal plants and their fractions

ABSTRACT Introduction: Medicinal plants belong to Lamiaceae family are potential sources of new drugs to improve the treatment of diseases which its treatment is linked to anti-oxidative agents. In this paper, antioxidant potentials of some Lamiaceae species have been evaluated by two methods. Methods: phosphomolybdate assay for total antioxidant capacity and ferric reducing a...

Investigation of Langmuir and Freundlich Adsorption Isotherm of Pb2+ Ions by Micro Powder of Cedar Leaf

ABSTRACTIn this work, the micro powder was the product of cedar leaf (MPCL) is used as a low-cost adsorbent for the removal of Pb2+ ions from aqueous solutions. Bath experiments were used to determine the best adsorption conditions The adsorption percentage of Pb2+ ions MPCL samples at different initial pH, contact time (tc), adsorbent dosage and temperature (T) were investigated. Effective rem...

Adsorption of Pb ( II ) , Ni ( II ) and Sr ( II ) Ions

of past research 1) The individual and competitive adsorption of metal ions on graphene oxides (GOs) studies by experimental and DFT calculation The heavy metal ions can be accumulated in living tissues, so they must be removed from polluted water. Graphene oxides (GOs) are considered as the ideal adsorbent material because the large quantities of oxygen-containing functional groups strengthen ...

Effect of Acid Treatment of Carbon Nanotubes on Their Adsorption Capacities of Benzene and Toluene

Toluene and benzene were eliminated using multi-walled carbon nanotubes (MWCNTs). In order to investigate influence of acid treatment on the MWCNTs adsorption capacities, the MWCNTs were functionalized by nitric acid (10 M) under reflux conditions for 2 h. Fourier transform infrared (FTIR) and Raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes su...
