Applied Environmental Research
Nano zero valent iron (NZVI) has been extensively studied for its application to treat pollutants, particularly in contaminated water. This research studies enhancement of the reducing power of NZVI using kaolin as a supporter and ethanol as a medium. Kaolin modified nano zero valent iron (K-NZVI) was synthesized under three different parameters including ethanol content (0-100 v%), ratio of kaolin to NZVI (0-1.5), and dropping rate of NaBH4 (4-10 mL/min). The Box-Behnken Design was used to design the experimental conditions, and Reactive Red 120 was used as an organic pollutant probe to quantify the reducing power of the synthesized K-NZVI. …
