Abstract:
Polyurethane foam (PUF) was physically functionalized with curcuminanddithizone
to adsorb Fe3+ ions, applying the off-line solid phase extraction procedure. The
concentrations of the metals have been determined using the molecular
spectroscopy. Various factors including, the pH of the sample solution and the time
of extraction were examined. The adsorption mechanism of metal 0ion onto coated
PUF was tested using the Morris-Weber and Lagergren equations. The capacity
sequence of the sorbent was in the order dithizone-PUF >curcumin-PUF
