Determination of iodate in waters by cuvetteless UV–vis micro-spectrophotometry after liquid-phase microextraction

A Highly Sensitive and Selective Method for the Determination of an Iodate in Table-salt Samples Using Malachite Green-based Spectrophotometry

“…The reaction time was shorter than a previous related work. 26 Thus, a reaction time of about 5 min is reasonable to obtain the highest yield. …”

“…There are various analytical methods for determining the content of iodine, iodide, and iodate in various samples, including redox titration using sodium thiosulfate, gas chromatography, ion-chromatography and high-performance liquid chromatography, [15][16][17][18][19] spectrophotometric methods based on methylene blue, 20 rhodamine B 21 and variamine blue 22 prior to measurement of its absorbance, kinetic spectrophotometric method, 23 spectrofluorometry, 24 flow-injection analysis, 25 microscale spectrophotometry followed by liquid-phase microextraction, 26 capillary ion chromatography, 27 inductively coupled plasmamass spectrometry (ICP-MS), [28][29][30][31][32] inductively coupled plasma optical emission spectrometry (ICP-OES), 33 and inductively coupled plasma atomic emission spectrometry (ICP-AES). 34 This paper describes a simple and sensitive UV-Vis spectrophotometry method for a highly selective trace determination of iodate.…”

A rapid assessment method for determination of iodate in table salt samples

“…Some of the recent methods include kinetic spectrophotometric methods (Ni and Wang 2007), flow injection analysis (Shabani et al 2011), microspectrophotometry after liquidphase microextraction (Pereira et al 2010), using cadmium sulfide quantum dots as fluorescence probes (Tang et al 2010), liquid-liquid microextraction by high-performance liquid chromatography-diode array detection (Gupta et al 2011), ion chromatography with integrated amperometric detection (Babulal et al 2010), transient isotachophoresiscapillary zone electrophoresis (Wang et al 2009), gas chromatography-mass spectrometry (Das et al 2004), using polymer membrane selective for molecular iodine (Bhagat et al 2008), and neutron activation analysis method (Bhagat et al 2009). A non-suppressed ion chromatography with inductively coupled mass spectrometry (ICP-MS) has been developed for the simultaneous determination of iodate and iodide in seawater (Zul et al 2007).…”

Spectrophotometric determination of iodate in iodised salt by flow injection analysis

“…Several analytical techniques have been reported for the determination of iodate, including spectrophotometry (Afkhami & Mosaed, 2002;Pena-Pereira, Senra-Ferreiro, Lavilla, & Bendicho, 2010;Silva, De Oliveira, & Neves, 1998), chemiluminescence (Zui & Terletskaya, 1995), ion chromatography (McTaggart, Butler, Haddad, & Middleton, 1994;Rebary, Paul, & Ghosh, 2010), gas chromatography-mass spectrometry (Reddy-Noone, Jain, & Verma, 2007;Shin, Oh-Shin, Kim, & Ryu, 1996), high performance liquid chromatography (Xu, Li, Gu, & Paeng, 2004), indirect atomic absorption spectrophotometry (Chakraborty & Das, 1989), transient isotachophoresis-capillary zone electrophoresis (Wang, Zhao, Shen, Tang, & Wang, 2009), and electroanalysis (Huang, Li, Chen, & Wang, 2008;Lin, 1999;Sharma & Songara, 2007). Most of these methods are either time consuming, or require complicated and expensive instruments, or are not very sensitive.…”
