This research aims to develop an electrode carbon paste-molecularly imprinted polymer (MIP) as sensor for the analysis of creatinine by potentiometric. The preparation of non-imprinted polymer (NIP) is done by mixing aniline, creatinine and potassium peroxodisulfate with mole ratio of 2:0.1:1. Creatinine is extracted from the polymer using hot water to form mold creatinine, this so-called MIP. In this study, the optimum electrode having composition made of activated carbon, paraffin, and MIP of 40:35:25 (mass ratio) and response time for 91-192 seconds. Nernst factor obtained from this study was 23.2 mV/decade, the measuring range of 10 -6 -10 -3 M, lower detection limit of 5.49 x 10 -6 M and the upper detection limit of 1.07 x 10 -3 M. The accuracy of methods for concentration of 10 -6 -10 -3 M was 76.40% -165.80% and the precision is expressed by the coefficient of variation for the concentration is 0.05% -0.32%. The electrodes are still well used up to 83 times of usage. Urea does not interfere with the performance of the electrode carbon paste-MIP on the analysis of creatinine.

“…Distribution coefficient (Kd) suggested the character of a substance adsorbed by a sorbent, selectivity coefficient of the sorbent (k) suggested the otherness of two substances adsorbed by one sorbent and relative selectivity coefficient (k´) suggested the otherness of two sorbents. These factors were calculated as the following formula (1)- (3).…”

Abstract.A novel surface imprinting material was synthesized using a template immobilized on Silica gel matrix by surface imprinting technique using naphthol as template, 3-isocyana to propyltriehthoxysilane as monomer, ethyl silicate as crosslinking agent. FTIR spectrum and scaning electron microscope were adopted for the characterization of the surface and structure of the molecularly imprinted absorbent. The separation and preconcentration characteristics of the imprinted absorbents for naphthalene were researched by batch procedures. The naphthalene molecularly imprinted adsorbent showed high adsorption capacity and significant selectivity for naphthalene.

“…However, none of these works is oriented towards sensor development. We have successfully developed a Cre sensor based on a MIPmodified hanging mercury drop electrode (HMDE) [11], and subsequently a highly sensitive and selective detection of Cre was feasible by the combined use of this sensor and a complementary molecularly imprinted solid phase extraction system [12]. Although MIP -modified HMDE was found to be appropriate for the analysis in laboratory setting, it was difficult for use as a portable transducer in electrochemical sensor for either on-line or in-field detection.…”

“…The MIP, poly(melamine-co-chloranil), chosen in the present work is same as that used for HMDE sensor reported earlier [11]. The firm adherence of MIP molecules over electrode surface is primarily because of sol-gel adhesion in between graphite surface and MIP film layer (Fig.…”

An electrochemical creatinine sensor based on a molecularly imprinted polymer (MIP)-modified sol-gel film on graphite electrode was developed. The surface coating of MIP over sol-gel was advantageous to obtain a porous film with outwardly exposed MIP cavities for unhindered selective rebinding of creatinine from aqueous and biological samples. A fast differential pulse, cathodic stripping voltammetric response of creatinine can be obtained after being preanodized the sensor in neutral medium containing appropriate amount of creatinine at þ 1.8 V versus SCE for 120 s. A linear response over creatinine concentration in the range of 1.23 to 100 mg mL À1 was exhibited with a detection limit of 0.37 mg mL À1 (S/N ¼ 3).
