Flow injection chemiluminescence determination of femtogram-level cobalt in egg yolk, fish tissue and human serum

A review on applications of chemiluminescence detection in food analysis

“…Because of its low adsorption rate and high excretion rate, Co toxicity is not common, but an excess can lead to enlargement of the thyroid gland [74]. Recently, Song et al [75] reported a CL method for the determination of Co in egg yolk, fish tissue and human serum. In their work, it was found that Co could greatly catalyze the CL reaction between luminol and dissolved oxygen, and the increment of CL was linear over the Co concentration ranging from 10 fg mL −1 to 50 pg mL −1 with a detection limit of 4 fg mL −1 (3 ) and relative standard deviation of less than 3.0%.…”

Cold-Induced Aggregation Microextraction: A Novel Sample Preparation Technique Based on Ionic Liquids for Preconcentration of Cobalt Prior to Its Determination by Fiber Optic-Linear Array Detection Spectrophotometry in Real Water Samples

“…Initial efforts to address the problem of large solvent consumption have led to a development of the FIE method. Some of these methods have been applied for cobalt extraction (Andac et al, 2001;Cao et al, 1999;Cassella et al, 2001;Dadfarnia & Jafarzadeh, 1999;Dzherayan et al, 2002;Fujimoto et al, 1999;Li et al, 2006a;Li et al, 2006b;Nogueira et al, 1998;Shabani et al, 2003;Song et al, 2006;Tsakovski et al, 2002). FIE has some advantages compared with LLE like low cost, high extraction speed and reduced solvent and sample consumption.…”

Determination of cobalt in water samples by atomic absorption spectrometry after pre-concentration with a simple ionic liquid-based dispersive liquid-liquid micro-extraction methodology

“…Several analytical techniques such as UV-Vis spectrometry [4][5][6], spectrofluorimetry [7], flow injection chemiluminescence (FI-CL) [8,9], electroanalytical techniques [10][11][12], laser induced thermal lens spectrometry [13], X-ray fluorescence [14], neutron activation analysis (NAA) [15,16], flame atomic absorption spectrometry (FAAS) [17][18][19], electrothermal atomic absorption spectrometry (ET-AAS) [3,20,21], inductively coupled plasma optical emission spectroscopy (ICP-OES) [22][23][24] and inductively coupled plasma mass spectrometry (ICP-MS) [25,26] have been reported for the determination of cobalt in different samples.…”
