Abstract

Toxic leadions removed efficiently from water by a newly fabricated, magnetically recyclable, antibacterial nano-Ag/γ-Fe2O3@GOadsorbent, at ambient and teh physiological pH=7. Teh adsorption depends on teh adsorbent dosage, initial Pb(II)concentration, pH and teh contact time. Teh optimum removal efficiency of teh leadion is found to be 93.1% wif a dosage rate of 20 mg/L, in 40 minutes, at pH 5 (to 14). Equilibrium data fits well wif teh Langmuir and Freundlich models wif a maximum adsorption capacity of 90.91 mg/g of Pb(II) per 20 mg/L of Ag/γ-Fe2O3@GO. Teh removal/uptake mechanism involves interaction between Pb(II) and teh oxide/hydroxyl layer around Ag/γ-Fe2O3@rGO, in teh contaminated water medium.
