Coordination of Lead (II) and Cadmium (II) Ions to Nylon 6/Flax Linum Composite as a Route of Removal of Heavy Metals

Abstract

Nylon 6 (PA6) reinforced Flax Linum composites were synthesized by melt mix extrusion and molded through Mucell\ ® injection technique for adsorption application for removal of Cd(II) and Pb(II) metal ions. The structural morphologies of all samples were evaluated using X-ray diffraction (XRD), Transmittance emission microscopy (TEM) and Scanning emission microscopy (SEM), indicating crystallized materials with pore-like cells and Thermographic analysis (TGA) illustrated the thermally stable., Microscopic PA6 revealed the effects of Flax content on both cell density and cell size of the foamed samples. The cell size of neat PA6 (48 μm) changed to 36, 17, and 15 μm after incorporation of Flax compositions for 1.0, 3.0 and 5.0 wt%.The removal of Cd(II)and Pb(II) with PA6/Flax 1.0 wt% composite was found to follow the Langmuir isotherm model. The results indicated that PA6 1.0 wt% composite can be efficiently used as a superabsorbent for the removal of Cd(II) and Pb(II) from aqueous solution.

“…Methods i.e. adsorption, ion exchange, coagulation, precipitation, membrane process and electrochemical approaches have been employed to reduce or remove heavy metal ions from wastewater Moja et al 2021;Perumal et al 2021). Development of an environmentally friendly adsorption process has extensively attracted the researchers' attention.…”
