Alkyd resins are highly branched polymer with a polyester backbone which considered as one of the important class of synthetic polymers 20. They are thermoplastic polyester resins can be synthesized by polycondensation 21 of three types of monomers of polyhydric alcohols (e.g; glycerol), dibasic acids (e.g; isomers of phthalic acid) or their anhydrides (e.g; phthalic anhydride) and fatty acids (e.g; oleic acid) 22-24. They can be dissolved in organic solvents and have good interactions with polar substrates such as wood and steel 25. They have excellent properties such as acceptable, inexpensive to produce, high gloss, retention color, dissolved in organic solvents, excellent thermal stability, eco-friendly, excellent wetting properties, good adhesion and good interactions with polar substrates such as wood and steel 26, 27. These properties make them suitable to apply in industrial coating, adhesives, the binder for composites and anticorrosion paint. Bio-alkyd resin contains reactive sites such as carbon-carbon double bond, a polar ester group, methylene group attached to the carbonyl site, allylic methylene attached to double bond 28.
The present paper approaches the study of OOBAR as a new biosorbent which used for Mo(V) sorption was synthesis. Properties of OOBAR are were characterized by UV-Vis, FTIR, and bulk DC electrical conductivity. The sorption of Mo(V) onto OOBAR was studied to optimize the best conditions for the sorption process. The obtained data have been examined for kinetic, thermodynamic, and equilibrium situations. Mo was applied in many pharmaceutical and biological areas including tissue of lever mice, tap water, and vitamin drugs.
