Study the electrical conductivity of cross-linked polymers in the pure and doped state

With in the frame of this work , cross-linked polymer prepared in different percents (25:75),(50:50%) and (0:100%) (glycerol:triethanol amine) which produced polymer I, polymerII and polymerIII consequently via condensation polymerization between glycerol and triethanol amine with malice anhydride.

Construction of Oxymetazoline Hydrochloride Selective Electrodes and Determination of Oxymetazoline in Pharmaceutical Drugs

Oxymetazoline hydrochloride ion selective electrodes were constructed. Construction was based on drug complex formation with dodeca-tungstophosphoric acid as ionophor and many plasticizer: Di –butyl phthalate (DBPH), Tri- butyl phosphate (TBP), O- nitrophenyloctylether (ONPOE), Di- octyl phthatale (DOP) in PVC matrix membranes. The matrix membrane was formed by mixing plasticizer and drug complexes with PVC.
