Abstract

There are great resources of natural zeolite in Iran. Zeolite, an inorganic ion exchanger, may be used as a suitable technical-economical solution for water treatment in many regions in Iran. In this research, the characterization of Zeolite in the east region of the country and the feasibility study for removal of hardness, cations and anions was investigated as follows: (1) determination of Zeolite composition and type by using X-Ray Fluorescence (XRF), thermal analysis and infrared spectrometer methods. (2) determination of cation exchange capacity (CEC) and its impact on water hardness reduction. Determination of isotherm curves for Fe, Cr, Al, Bi, Cd, Mn, Ca, Mg, Ag, Ni, Zn, Cu, Pb and their disposition to Zeolite phase, also determination of removal rate of the mentioned cations in analyzed water samples. (3) Zeolite structure rectification by using surfactant (HDTMA) for anions removal. Keywords: natural Zeolite, characterization, water treatment, cations and anions removal.
