Sodium Alginate-Cellulose-Nano-Clay Composite Adsorbent Applied for Lead Removal from Wastewater

Abstract

A sodium alginate/cellulose/n-clay composite was prepared as potential adsorbent for removal of Pb(II) from wastewater. The results showed that obtained adsorbent used for 4 mg L-1 initial concentration of Pb(II) in wastewater after 90 min adsorption time led to 90% removal efficiency and the adsorption capacity of the prepared composite was 0.11 mg .g-1. The isotherms and kinetics of adsorption revealed that the equilibrium adsorption and kinetics were well-described by the Langmuir model and pseudo-second-order kinetics, respectively.

Artificial Neural Network Modeling for Removal of Cd (II) and Pb (II) from Wastewater by Using Three Ferrite Nanomaterial (Cu0.9Zn0.1Fe2O4, Cu0.8Zn0.2Fe2O4, and Cu0.7Zn0.3Fe2O4) and Study the Antimicrobial Effectiveness of these Ferrite Substances

“…It can notice that when taking the optimal pH, the adsorption of Cd (II) and Pb (II) increased rapidly with the contact time on all three adsorbents. For cadmium ions at optimum pH and 0.1 g adsorbent dose for 45 min gave an excellent removal of 100% on both adsorbents (A and B), and for adsorbent (C) was 95%, and for lead (II) removal when in optimum conditions when increasing contact time leads to increases the removal efficiency [30].…”

Experimental and modeling studies of the effects of nanoclay on the oil behaviors in a water–sand system

“…To address these concerns, common methods for removing heavy metals from water sources, including membrane filtration, activated carbon adsorption, and electrocoagulation have been used for removing heavy metals from water (Joseph et al, 2019). For instance, a novel nanocomposite was implemented to investigate the removal of Pb (II) from water (Matei et al, 2020). This nanocomposite was synthesized by mixing sodium alginate, nanoclay (H2Al2O6Si), Microcrystalline cellulose, and Calcium chloride.…”
