The JASCO FTIR-4100 spectrometer in the 4000–400 cm-1 regions by using KBr disc (KBr pellet) was carried out the characterization of olive bio-alkyd resin. The absorbance measurements of Mo(V) complexion were determined by using JASCO (V-630 UV-VIS Spectrophotometer, Japan) at ?max 485. Bulk DC conductivity was established using Keithley, 6517B electrometer-high resistance meter after pressing OOBAR disk by a Hydraulic press at 12 tons. Dynamic technique for chromatographic separation experiments was carried out by using a glass column with a bed height of 15 cm approximately that contained 9.5 g of OOBAR was 35 cm long and 1.5 cm in diameter.
Olive biosorbent (OB): Olive tree legs and green leaves were cut to small particle size followed by washing with water, drying at 250 ?C and blending using food blender. Carboxy olive biosorbent (COB) preparation: 100 g of OB with 80 mL of concentrated HNO3 were heating in a beaker until brown foams finished, then washing with distilled water and methanol then drier at 80 ?C.
Olive/oleic bio-alkyd resin (OOBAR) Preparation: A 85 g of oleic acid with 28 g of glycerol were heated for 6 h. Then the product was heated with 15 g biosorbent 6 h, followed by adding 15 g of phthalic anhydride then heated 6 h. The final product was washed with distilled water then methanol and left to dry at room temperature then blending and sifting at 355 µm (0.0355 cm).
Molybdenum stock solution (1 g/L): was prepared by dissolving 0.185 g of (NH4)6Mo7O24.4H2O in distilled water to 100 mL.
