Abstract

Adsorption to the biological polymers (LCNFs and CNFs) is a novel environmentally friendly technology for reducing and removing Heavy metals from industrial wastewater. The goal of this study was to investigate and compare the performance of LCNFs and CNFs Adsorbents in the removal of lead from aqueous solutions in a discontinuous system. The test conditions are considered completely identical for the two Adsorbents. Infrared spectrometer (FT-IR) and transient electron microscopy (TEM) were used to identify the physical, chemical and structural characteristics of LCNFs and CNFs Adsorbents. In the discontinuous system, pH (4-9), absorption dose (0. 1-1 g L-1), contact time (15-120 min)., lead initial concentration (10-50 mg L-1) and temperature (15-40° C) were studied. The results were analyzed by one-way ANOVA and Duncan's tests for significant evaluation of changes in parameters. Results showed that the highest percentage of removal of lead (98. 45%. ) for LCNFs obtained at 25 ° C, pH 6, 60 min., absorbent dose of 0. 3 g L-1 and lead concentration of 10 mg L-1. The LCNFs and CNFs Adsorbents are considered as optimal absorbers for removal of lead from aqueous solutions.
