Adsorption of Lead(II) Ions from Aqueous Solution onto Lignin
Autor: Laura Bulgariu, Dumitru Bulgariu, Theodor Malutan, Matei Macoveanu
Publikováno v: Adsorption Science & Technology, Vol 27 (2009)
The adsorption of lead(II) ions from aqueous solution onto lignin was investigated in this study. Thus, the influence of the initial solution pH, the lignin dosage, the initial Pb(II) ion concentration and the contact time were investigated at room t

Valorisation of romanian peat for the removal of some heavy metals from aqueous media
Autor: Catalin Balan, Matei Macoveanu, Laura Bulgariu, Dumitru Bulgariu
Publikováno v: Desalination and Water Treatment. 52:5891-5899
In this study, the sorption of some potential toxic heavy metal ions (Pb(II), Hg(II) and Cd(II), respectively) onto Romanian peat was investigated as a function of initial solution pH, sorbent dose, initial metal ions concentration and contact time,
