چکیده مقاله:

: A new fibrous adsorbent was prepared by grafting Acrylic Acid /Acryl Amide (AA/AAm) co-monomers onto Poly(Ethylene Terephtalat) (PET) fibers. The resulting sorbent has been characterized by Fourier Transform InfraRed spectroscopy (FT-IR), Thermo Gravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and elemental analysis and studied for the preconcentration and determination of trace Pb+2 ion from water sample. The effects of reaction conditions such as monomer mixture ratio, grafting yield, polymerization. The time and temperature on grafting were investigated. Batch adsorption method was used for the  pre concentration studies. Recovery of Pb+2 was 100.2% at optimum conditions. The adsorption capacity of the adsorbent was found 44.1mg/gforPb+2.

MODIFICATION OF CLINOPTILOLITE BY SURFACTANTS FOR MOLYBDATE (99Mo) ADSORPTION FROM AQUEOUS SOLUTIONS

Experiments were conducted to study the ability of surfactant-modified clinoptilolite for molybdate adsorption from aqueous solutions. Clinoptilolite was treated with some cationic surfactants. Adsorption of surfactants on zeolite surface was confirmed by chemical analysis, IR (Infra-Red Spectroscopy), DTG (Derivative Thermogravimetry) and SEM (Scanning Electron Microscopy) techniques. The modi...

SURFACE MODIFICATION OF ANALCIME FOR REMOVAL OF NITRITE AND NITRATE FROM AQUEOUS SOLUTIONS

The capacity of natural zeolites to absorb anionic pollutants from water is limited. This limitation can be overcome by modifying the surface of the minerals with organic cations. In this research, natural zeolite, Analcime was used for removing the nitrate and nitrite impurities from aqueous solutions. The surface of the zeolite was modified by tetramethylammonium and tetraethylammonium ions t...
