Supra molecular mechanism of the removal of 17-β-estradiol endocrine disturbing pollutant from water on functionalized iron nano particles

β-Estradiol residue in water is very dangerous and unacceptable due to its endocrine disturbing and carcinogenetic nature. Therefore, fast, effective and eco-friendly removal method of β-estradiol is described from water. The maximum removal of β-estradiol from water was 82% with 600 μg L− 1 amount of 17-β-estradiol, 60 min agitation time, 6.0 g L− 1 amount of functionalized iron nano particles, 11.5 pH and 25 °C temperature. Thermodynamic parameters confirmed the spontaneous and exothermic uptake of 17-β-estradiol. The uptake of 17-β-estradiol followed first order reaction and the mechanism of uptake was through liquid film diffusion. The supra-molecular mechanism of β-estradiol interaction with functionalized iron nano particles is described. The reported method is fast, effective and eco-friendly and can be applied for the uptake of β-estradiol from water at laboratory, pilot and industrial levels in any water system.
