    關鍵字: Nano zero-valent iron (NZVI) has been extensively researched for treatment of hazarsous and toxic wastes. In particular, it can be applied to remediate contaminated sites directly. In this study, the NZVI was synthesized by using chemicals of NaBH4 (3.3-10 mL/min),and agitation power (200-300rpm). Right after completion of NZVI particles of different varieties, nitrate of 100 ppm was used to probe its reducing power. Of these three parameters investigated, it appears that the agitation of reaction solution plays a major role in determining its reducing power of NZVI particles. Besides, air exposure of reaction also posed noticeable change on the final residue of nitrate, whereas the synthesis with the studied range of NaBH4 feeding rate exhibited no significant effect on nitrate reduction.
