Title: Efficient pollutant removal in wastewater using nanosized zero-valent iron: Mechanisms and applications
Abstract: This work investigated the removal of zinc (Zn), methylene blue (MB), and lead (Pb) using nanosized zero-valent iron (nZVI). The analysis of variance (ANOVA) indicated that the second-order polynomial was a highly suitable model for removing pollutants. The specific surface area, pore diameter, and pore volume average of the nZVI were 16.4 m2 g−1, 40.1 Å, and 0.012 cm3 g−1, respectively. Under optimal conditions (pH = 7, concentration = 15 mg L−1, nZVI amount = 0.039 g, and ultrasound time = 10 min), the removal of Zn, MB, and Pb was 91.74 %, 95.60 %, and 95.16 %, respectively. The reusability study demonstrated that the nZVI can be utilized for 5 cycles of adsorption/desorption. In addition, nitric acid was selected as the optimum eluent among the different eluents. The analysis of environmental water samples revealed that the nZVI adsorbent has an acceptable ability to remove heavy metals and dyes from environmental water samples.
