Rezultati prikazani u ovom radu pokazuju da se pšeniĉna slama kao ekonomski isplativ, prirodan adsorbens
moţe uspešno koristiti za adsorpciju Pb 2+ ‒jona iz vodenih rastvora. Maksimalni kapacitet adsorpcije postiţe
se nakon 90 minuta procesa i iznosi 9,3 mg g -1 . Proces adsorpcije je brz, ravnoteţa se postiţe nakon 30 min
procesa i uspešno se opisuje kinetiĉkim modelom pseudo-drugog reda. Pokazalo se da Temkin-ova izoterma
na osnovu vrednosti regresionog koeficijenta (R 2 ≈0,97) dobro opisuje adsorpciju Pb 2+ ‒jona na slami.
