Use of Dicloxacillin Al(III) Complex as a Modifier for Determination of Al(III) Ion in Real Samples

Abstract

Three new modified electrodes based on a wellcharacterized Al(III)-Dicloxacillin complex (Dicloxacillin: penicillin antibiotic) in the form of carbon-paste, PVC and coated graphite were fabricated and investigated for determination of Al(III) ions in multivitamin syrup, tap water and soda cans. The developed sensors showed excellent sensitives to Al(III) ions with slopes in the range of 16.77-20.00 mV/concentration decade and detection limits of 4.04 × 10 À 4-3.16 × 10 À 7 mol L À 1 as well as fast response time of 10-20 s. The electrodes were effectively applied as indicators in the potentiometric titration of Al (III) with disodium hydrogen phosphate.

Selective Membrane Sensor for Aluminum Determination in Food Products, Real Samples and Standard Alloys

“…Utilities of electrode sensors have developed to use in different ways [7][8][9]. Many techniques, like, atomic absorption spectrometry; AAS [10][11][12][13][14][15][16], spectro-fluorometry [17,18], chromatography [19][20][21][22], a laser diode atomic absorption spectroscopy [23], inductively coupled plasma-atomic emission spectrometry; ICP-AES [24][25][26], inductively coupled plasma-mass spectra; ICP/MS [27][28][29][30], spectrophotometry based on use of various reagents [31][32][33][34][35][36][37][38][39][40][41], ion-selective electrode techniques [42][43][44][45][46][47][48][49][50][51][52] and other recently different methods [53]…”
