Impact of polyhexamethylene guanidine on filtering of Pb(II) and Cd(II) hydroxides from aqueous solutions

Adsorption and co-adsorption mechanisms of p-nitrophenol and Pb(ii) on magnetic carbon aerogel in water

“…Besides, two newly appeared peaks at 660 cm −1 and 1211 cm −1 in the spectrum of 10% Fe-MCA after adsorbing Pb(II) are attributed to the formation of Pb-O. 49 Combining with the result of XPS, it can be inferred that Pb(II) can coordinate with O of hydroxyl of 10% Fe-MCA.…”
