چکیده
|
Toxic leadions removed efficiently from water by a newly fabricated, magnetically recyclable, antibacterial nano-ag/γ-fe2o3@goadsorbent, at ambient and the physiological ph=7. the adsorption depends on the adsorbent dosage, initial pb(ii)concentration, ph and the contact time. the optimum removal efficiency of the leadion is found to be 93.1% with a dosage rate of 20 mg/l, in 40 minutes, at ph 5 (to 14). equilibrium data fits well with the langmuir and freundlich models with a maximum adsorption capacity of 90.91 mg/g of pb(ii) per 20 mg/l of ag/γ-fe2o3@go. the removal/uptake mechanism involves interaction between pb(ii) and the oxide/hydroxyl layer around ag/γ-fe2o3@rgo, in the contaminated water medium.
