New chlropheniramine maleate (CPM) selective electrochemical membranes were prepared by using chlropheniramine maleate -molecularly imprinted polymers. MIP was prepared by bulk polymerization using 2-hydroxyethyl methacrylate (2-HEMA) as monomer, ethylene glycol dimethacrylate (EGDMA) as a cross-linker and a benzoyl peroxide (BPO) as an initiator at 600C.  Three CPM-MIP electrodes were constructed by using tri-tolyl Phosphate (ToCP), tris (2- ethyl hexyl) Phosphate (TEHP) and tributyl Phosphate (TBP) as plasticizers in PVC matrix.Electrode parameters including slopes, working concentrations ph. The interference effect in the presence of (Na+, Mg+2, Al+3, Glycine, Alanine, Arginine and Phenylalanine) was studied using the separated and mixed methods to determine the selectivity coefficient determination. NIP prepared by using the same composition of MIP molecularly imprinted polymer electrodes except the template (CPM). The slopes of CMPMIP are 21.00, 21.50 and 19.08 mV/ decade, linearity range for the electrodes around. (10-5 10-1) M, the stable at a pH range from 4.0 to 8.5 and lifetime ranged from 30 to 10 days. The suggested electrodes were successfully applied for the determine of CPM in some pharmaceutical preparations, which were given acceptable accuracy.

Abstract Four electrodes were synthesized based on molecularly imprinted polymers (MIPs). Two MIPs were prepared by using tramadol hydrochloride (TRH) as the template, acryl amide (AA) and 2-hydroxy ethyl meth acrylate (2-HEMA) as monomers, divinyl benzene as a cross linker, and benzoyl peroxide as initiator, respectively. The same composition was used to prepare non-imprinted polymers (NIPs), but without the template (Tramadol hydrochloride). Different plasticizers were employed to prepare the membranes; tris (ethyl hexyl) phosphate (TEHP), tri Butyl phosphate (TBP), di-octyl phthalate (DOP) and nitrobenzene (NB) in PVC matrix. The electrode characteristics and properties were studied, including: slope, detection limit, life time and linearity range. The results of selectivity coefficient measurements using amino acids as interfering species showed no effect on tramadol electrode response. The prepared electrodes were intended for use in determining tramadol in pharmaceutical samples
