The aqueous environment using natural clay minerals found around Siirt have tried to remove heavy metals such as Cu (II), Pb (II) and Cd (II)

In this study, the aqueous environment using natural clay minerals found around Siirt have tried to remove heavy metals such as Cu (II), Pb (II) and Cd (II). To that end, a natural clay mineral Siirt around was characterized by FTIR, SEM, EDX, X-ray (XRD and XRF) TGA-DTA and BET technics. The different parameter such as pH, temperature, amount of adsorbent, the particle size the metal concentration and contact time was evaluated. Also adsorption parameters (k, n, As, Kb) of the Freundlich and Langmuir isotherm and thermodynamic parameters (ΔH and ΔG) is calculated. Metal concentration remaining in solution was performed with a Perkin Elmer 700 spectrometer device. The obtained results showed Siirt found around natural clay minerals can be used as adsorbent. Also affecting the adsorption pH, temperature, amount of adsorbent, the increase in metal concentration and time was observed to increase the sorption parameters.
