Preparation and Characterization of Lecithin-Nano Ni/Fe for Effective Removal of PCB77

Table 1

Data arose from the analysis of BET surface area.

Sample	𝑆BET (m^2/g)	Pore volume; (cm^3/g)	Pore diameter; (nm)
Lecithin-nano Ni/Fe	16.24	0.0694	17.10
Nanolecithin	15.38	0.0542	14.10
Lecithin powder	1.725	0.00201	4.66
