Abstract

In the present work, modification of phosphate dolomite was conducted and applied for some bivalent metal ions removal. Physico-chemical properties of sorbent were characterized by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential-thermal analysis (DTA), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and low temperature adsorption-desorption of nitrogen. Sorption properties of modified dolomite for Zn²⁺, Fe²⁺, Cu²⁺, Pb²⁺, Cd²⁺, Ni²⁺ and Co²⁺ removal were studied using model solutions. The highest removal efficiency was observed in pH range from 2 to 5. Among all tested metals, highest adsorption capacity of phosphated dolomite was detected towards Co²⁺ and Pb²⁺ (15 and 12 mmol g^-1, respectively) and the lowest towards Zn²⁺, Fe²⁺ and Cu²⁺ (about 8 mmol g^-1). Adsorption isotherms were built for each tested metal ions and were fitted to Langmuir, Freundlich and Redlich-Peterson models.
