“…There are many methods for the low-level Gd monitoring in solution. Most of them are spectroscopic methods such as spectrofluorimetry (Reisfeld and Biron 1970;Taketatsu and Sato 1978;Berg, Mainka, and Ache 1989;Hu et al 1997), spectrophotometry (Mori et al 1992), ICP-AES (Normann et al 2000), Novel Gadolinium Optical Sensor 191 ICP-MS (Behrens 1995;Cao, Yin, and Li 1999;Hennebruder et al 2004;Isnard et al 2005), LC (Winget and Lindstrom 1971), electron spin resonance (ESR) (Moyer and McCarthy 1969;Miyake and Imoto 1996;Miyake, Kanamaru, and Imoto 1986), laser-based multistep resonance ionization MS (Blaum et al 2002), phosphorescence (Gong and Zhang 1997), and some neutron activation methods (Marsh and Allie 1969;Jinno et al 1979). These methods have either low sensitivity, are time-consuming, involving multiple sample manipulations, or are too expensive for most analytical laboratories.…”

In this work, for the first time we report a highly selective and sensitive Gd(III) optical sensor based on immobilization of (Z)-N 0 -((pyridine-2-yl) methylene) thiophene-2-carbohydrazide (PMTC) on a triacetylcellulose membrane. This optode exhibits a linear range 5.0 Â 10 À8 to 2.0 Â 10 À5 M of Gd(III) ion concentration with a detection limit of 1.1 Â 10 À8 M. The response time of the newly designed optode was within 1-2 min, depending on the Gd(III) ion concentration. The response of the sensor is independent of the pH solution in the range of 2.0-9.0. It manifests advantages of low detection limit, fast response time, and most significant, very good selectivity with respect to a number of lanthanide ions (La, Ce, Sm, and Eu ions). The proposed sensor could be successfully regenerated with a thiourea solution. Its response was reversible and reproducible (RSD less than 1.3%). This optode was applied to the determination of Gd(III) in synthetic and real samples.

“…Determination of Gd in various environmental matrices can be carried out by using different analytical methods such as inductively coupled plasma-optical emission spectrometry/mass spectrometry (ICP-OES/MS) [9][10][11], electron spin resonance (ESR) spectroscopy [12,13], fluorescence [14], time-resolved fluorimetry [15], nuclear methods [16] and potentiometric methods [6,[17][18][19], etc. Most of these methods involve high-cost instruments, trained manpower, tedious sample preparations and are often time consuming.…”

“…[3]. Different analytical techniques such as inductively coupled plasma mass spectrometry (ICP-MS) [4][5][6][7][8], electron spin resonance (ESR) [9,10], spectrofluorometry [11,12], electrochemical sensor [13,14,2,15,16] and neutron activation analysis [17] have been performed to determine Gadolinium in various samples. Usage of spectrophotometry for determination of Gd(III) is very suitable because this method is the inexpensive and available in all laboratories.…”

A solidified floating organic drop microextraction (SFODME) combined with UV-Vis spectrophotometry was applied for preconcentration and determination of Gd(III). In this study, Morin (3, 5, 7. 2', 4' pentahydroxy flavone) as a suitable ligand and 1-Dodecanol as extraction solvent were used. Following the extraction Gd-Morin complex, the extraction solvent was transported to a spectrophotometer for determination of Gadolinium ion at the absorption wave length of 440 nm. The main affecting factors in the performance of SFODME such as pH, concentration of Morin, extraction time, stirring rate and sample volume were investigated and optimized. Under the optimum conditions, the enrichment factor of 23, linear dynamic range of 80-900 µg L -1 with correlation of determination (R 2 >% 99) and limit of detection of 172µg L -1 were obtained for determination of Gd(III). The relative standard deviation (n = 5) for 150 µg L −1 of Gd(III) (sample volume 4.0mL) was ±2.17%. The method was successfully applied for preconcentration and determination of Gd(III) in water samples.
