“…Consequently, we decided testing the impregnated long chain primary amine (CH3(CH2)11NH2 ) (dodecyl amine) [17] onto the polyurethane foam [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] for the co-adsorption of uranium and thorium from Egyptian monazite sulfate solution. The studied relevant factors affecting uranium and thorium sorption onto the solvent impregnated foam included contact time, initial uranium and thorium concentrations, solution pH and reaction temperature.…”

Uranium and thorium were progressively co-adsorbed from the acid solution of Egyptian monazite utilizing dodecyl amine impregnated foam. As a function of contact time, initial uranium and thorium concentrations, pH and adsorption temperature. The attained informations of uranium and thorium co-adsorption were fitted well with Langmuir isotherm. The computed adsorption capacity of the studied adsorbent is around 1250 and 1430 mg/g for uranium and thorium individually. Uranium and thorium were effectively isolated from the loaded adsorbent by utilizing NaCl acidified with H2SO4 and H2SO4 as effective solutions for their elution individually.

“…Activated carbon is a commonly used adsorbent for the removal of pollutants that are present in water and waste water, but its high cost has restricted its more widespread use. A variety of natural sorbents has been exploited for the sorption of toxic metal ions from aqueous systems [6–9].…”

The aim of this research was to investigate the sorption characteristics of polyaniline/sawdust (PAn/SD) for the removal of Zn(II) ions from aqueous solutions. Batch sorption studies were carried out to determine the effect of initial concentration of the sorbate, agitation time, adsorbent dose, and pH on the removal of Zn(II). The sorptive removal was found to be strongly pH‐dependent. The experimental data fitted well to the Freundlich isotherm. The products were investigated in terms of morphology and chemical structure by using scanning electron microscopy and Fourier‐transform infrared spectroscopy, respectively. Also, PAn/SD was used for the removal of heavy metals from urban waste water. J. VINYL ADDIT. TECHNOL., 2011. © 2011 Society of Plastics Engineers

Water is very important for life on earth. Heavy metals are unpleasant, affecting our ecosystem due to their toxic and physiological effects on environment 1. Main heavy metals are Cd(II), Pb(II), Cr(VI), Hg(II), Cu(II) and Ni(II). Among them, lead is very toxic even in very low concentration in water 2. Most elusive environmental health threat is the lead contamination as lead exposure is linked with death and disease in animals humans and birds. Most important sources of pollution by lead are: battery manufactures, automobiles, radioactivity shields, plumbing fixtures, cable coverings, ammunition, paint pigments, caulking, solder, printed circuit boards, bearings, textile industries, petroleum industries and electroplating 3,4. Rivers and streams are contaminated with its elevated levels. Leaching from soil is the natural cause of this metal contamination, but it is augmented due to above mentioned sources i.e. industrial waste water runoff or mine tailing 5. Concentrations of Pb(II) ions are about the range of 200-500 ppm in industrial waste water. According to water quality standards it is very high and it must be reduced to value of 0.10-0.50 ppm 6. Main target of lead in an organism body is CNS, kidney, liver and reproductive system. Its toxic symptoms are insomnia, anemia, dizziness, headache, irritability, weakness
