The molecular imprinting technique necessitates a synthetically prepared polymer matrix to form cavities sculpted around the template molecules of the same kind. MIPs are easy to prepare, stable, inexpensive and capable of molecular recognition. In this study, a MIP based carbon paste electrode (CPE) has been prepared for sarcosine determination and fully characterized in terms of composition, usable pH range, response time. The electrode has been applied for the potentiometric determination of sarcosine with relative standard deviations of 5.7 %. The modified electrode has been shown the lineer concentration range of 10−6 to 10−2 mmolL−1 with the limit of detection 0.70×10-6 mmolL−1 at the pH 5.0. The electrode has exhibited good selectivity for sarcosine according to a glycine. The proposed potentiometric method has been offered the advantages of simplicity, accuracy, automation feasibility and applicability to turbid and colored sample solutions.
