Simultaneous catalytic-fluorimetric determination of copper and mercury by flow-injection analysis

Kinetic Determination of Mercury(II) at Trace Level from Its Catalytic Effect on a Ligand Substitution Process

“…Most of these involve oxidation reactions [11][12][13][14][15][16][17][18][19], while references based on ligand substitution reactions are scarce [20][21][22][23][24]. In many cases, the inhibitory effect of mercury(II) on catalytic indicator systems [11][12][13][14][15] or of the catalytic action of mercury(II) on slow redox processes [16][17][18][19] has been utilized to develop CKMs for the determination of mercury(II). Pirvutoiu et al [13] developed a highly sensitive method for the determination of mercury(II); however, the method uses a costly enzyme as a substrate and a hard-to-find thermometric detection system.…”

Kinetic‐Catalytic and Spectrophotometric Determination of Hg(II) Using its Catalytic Effect on Ligand Substitution Reaction between Hexacyanoferrate(II) and Pyrazine

“…These methods have been found to be cheaper and more reliable alternative to the instrumental methods of analysis for trace determinations. [15][16][17][18][19][20][21][22][23] On contrary, the references on mercury(II) determination based on ligand substitution reactions are limited. [15][16][17][18][19][20][21][22][23] On contrary, the references on mercury(II) determination based on ligand substitution reactions are limited.…”

Construction and evaluation of an automated flow injection‐stopped flowanalyser for multipoint reaction rate spectrophotometric methods. Determinationof ammonia nitrogen, creatinine and phosphate

“…This technique, in combination with the merging zones principle [5] [5] and urea [11], ethanol in blood and spirits [12], glycerol and triglycerides [13], and the activity of the enzymes galactic dehydrogenase [10], alkaline phosphatase, lipase, acetylcholinesterase and chymothripsin in plasma and serum [14], have been determined. FI-SF in conjunction with catalytic reactions has been used in the determination of various ions, such as Co(II) [15], cyanide [16], Cu(II) in foodstuffs [17], and Cu(II) and Hg(II) simultaneously [18]. Comparative studies revealed that in the determination of Cu(II) [17] [7,9,10,12,[16][17][18]20,21 ].…”

Comparative studies revealed that in the determination of Cu(II) [17] [7,9,10,12,[16][17][18]20,21 ]. A variation of the fixed time approach utilizing the mean of absorbance pairs has also been described [13,14].…”
