Modification and characterization of PET fibers for fast removal of Hg(II), Cu(II) and Co(II) metal ions from aqueous solutions

Preparation of porous resin with Schiff base chelating groups for removal of heavy metal ions from aqueous solutions

“…The average pore diameter was found to be 4.45 nm. The surface area was relatively lower than for inorganic or hybrid adsorbents, but it was similar to that of other chelating polymers [35].…”

Highly effective removal of Cu(II) by triethylenetetramine-magnetic reduced graphene oxide composite

“…Langmuir k1 (l mg −1 ) 0.277 Q cal (mg g −1 ) 210.97Qexp (mg g −1 ) 209.01R 2 0.998 Freundlich k f (mg 1−n l n g −1 ) 81.375 n 4.834 R 2 0.965 [51][52][53][54][55][56][57][58] (Table 1), one can observe that TET-MRGO composite presents a fairly high adsorption capacity compared to other tested materials.…”

Synthesis and characterization of uranyl ion-imprinted microspheres based on amidoximated modified alginate

“…The ease of performance as well as the availability of the adsorbents, made the adsorption technique one of the most preferred extraction technique, particularly from the economic point of view [1]. Different materials such as clay [15], modified natural polymers like chitosan [16,17] and cellulose [18], in addition to modified synthetic polymer like PET [19,20] were extensively utilized as an effective adsorbents reducing the heavy metal contents in aqueous media. Among these types of adsorbents polysaccharide biopolymers such as alginate have displayed an obvious efficiency as a bio-adsorbent for such aquatic pollutants [21][22][23].…”
