Lead metal ions remediation in vitro, using centrifuge-assisted pectin extract a polysaccharide-based biomolecule.

Abstract

Sorption of heavy metal ions by different pectin-rich materials such as waste citrus peels and pectin extracts is emerging as a low-cost and double-headed solution technique for metallic contaminant removal and biomass solid waste management. Heavy metal ions present in drinking water and foods have remained a challenge, as the technology to thoroughly remove such heavy metal ions has remained on a higher side of the cost. Nonetheless, the effect of heavy metals on the health of humans taking contaminated water and foods has remained a constant silent threat. The results are almost certainly fatal with many instances a victim hardly knows the cause, as there is no immediate effect after their consumption. This research focused on evaluating the binding efficiency, spectroscopic characterization and extent of sorption. The study investigated the removal of lead, by pectin extract from orange peel wastes. The centrifuge-assisted pectin extract was chemically and spectrometrically characterized, for molecular conformity. The sorption of heavy metal depended on the mass of pectin, pH, and contact time. Uptake was rapid with equilibrium reached after 60 minutes with high removal of lead solution at pH 5 with efficiency of 71.0 %.
