Optimized Synthesis of FeS Nanoparticles with a High Cr(VI) Removal Capability

Figure 9

Removal of Cr(VI) in water solution by synthesized FeS nanoparticles. Initial Cr(VI) = 50 mg/L, FeS-to-Cr(VI) molar ratio = 0.8. Data plotted as mean of duplicates and the error bars (calculated as standard deviation) indicate data reproducibility.
