GJ - Privredna komora Srbije

Eksperimentalni podaci su pokazali da je maksimalni kapacitet adsorpcije Pb 2+ ‒jona na trini 9,6 mg g -1 .
Kinetika adsorpcije predstavljena je jednaĉinom pseudo-drugog-reda, a Freundlich-ova izoterma se pokazala
kao pogodna za predstavljanje ravnoteţne adsorpcije. Kapacitet adsorpcije jona bio je neznatno veći na
sitnijoj frakciji trine, ali se moţe zakljuĉiti da granulometrijski sastav trine nije bitno uticao na kapacitet
adsorpcije. Na osnovu eksperimentalnih podataka, trina se moţe okarakterisati kao pogodan adsorbens za
uklanjanje Pb 2+ iz otpadnih voda.
