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 remaining concentrations of Mo(V) were determined by using JASCO (V-630 UV-VIS Spectrophotometer, Japan). 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
