In this study, Revised 17 January 2018 nZVI was modiﬁed with sulﬁde to enhance Cd(II) removal from aqueous solutions. TEM and SEM analyses Accepted 7 February 2018 showed that sulﬁde-modiﬁed nZVI (S-nZVI) had a core-shell structure of nano-sized spherical particles, Available online 17 February 2018 and BET results proved that sulﬁde modiﬁcation
