study on sorption of some toxic and heavy ions in dilute solutions by clinoptilolite
نویسندگان
چکیده
the deposits of clinoptilolite (cli) in iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. the results showed that the absorption for ca2+ (7.5 ppm), cu2+ (50 ppm), zn2+ (40 ppm), cd2+ (40 ppm), pb2+ (500 ppm) and al3+ (5 ppm) were 95.2, 96.70, 93.30,99.12, 99.2 and 90.0 percents, respectively. the noteworth of our method in eliminating of contamination and conversion of waste water to drinking water is discussed in this report.

متن کاملSorption of Heavy Metal Ions from Aqueous Solutions: A Review
Sorption techniques are widely used to remove heavy metal ions from large volumes of aqueous solutions. Herein, the natural and some artificial materials, such as clay minerals, biosorbents, carbon-nanomaterials, metal oxides, are reviewed as adsorbents in the removal of different heavy metal ions, such as Ni(II), Cu(II), Pb(II), Cd(II), Cs(I), Eu(III), Th(IV), Cr(VI) from large volumes of aque...

15 صفحه اولHeavy 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 کاملSelective Sorption of Heavy Metal Ions from Aqueous Solutions Using m-Cresol Based Chelating Resin and Its Analytical Applications
Salicylic acid-Formaldehyde-m-Cresol (SFM) terpolymer had been synthesized in DMF media by conventional method. The resulting resin had been characterized by FTIR spectra, elemental and thermogravimetric analyses. The morphology of SFM resin had been studied by SEM and Optical photograph. Various parameters like rate of equilibration, effect of pH on ion exchange capacity and effect of conc...
