The results from the BET surface area analyzer give a SSA value of 15 524 m 2 /kg. Through Eq. (6), with the density of iron taken as 7870 kg/m 3, the average diameter of the nZVI particle is then obtained as 49 nm. The nZVI particle also exhibits a porous surface as shown in Fig. 2 (b). The BET result also disclosed that the average pore …
