N-bromosuccinimide as a direct titrant for thiourea and thioacetamide using bordeaux red as an indicator

Anodic Voltammetry of Thioacetamide and its Amperometric Determination in Aqueous Media

“…TAA hydrolysis [18][19][20], the use of TAA as precipitant reagent, as well as the various methods of quantitative determination by precipitation [21,22], amperometric or coulometric titration [23][24][25], redox reactions [26,27], potentiometry [28], utilization in precipitation and determination of various elements [29][30][31][32], anodization of mercury [33], cathodic stripping voltammetry [34,35], and even determination of TAA and a series of other thioamides by anodic voltammetry at solid metal electrodes [36,37], and associated problems concerning sulfide and H 2 S electrochemical oxidation or detection [38,39] have been experimented or applied. The common solid electrodes have rarely been tested for anodic determination of thioamides, with the exception of the application of pulsed amperometric detection (PAD) method [36] and new direct applications, such as determination of organic sulfur-containing compounds [3,40,41] and sulfide oxidation [38] at BDD, determination of thiourea at a BDD electrode [3] or thiourea at a copper oxide-copper electrode [2].…”

Mechanistic and Electrochemical Investigation of Catechol Oxidation in the Presence of Thioacetamide: Application for Voltammetric Determination of Thioacetamide in Aqueous Media

“…Acute and chronic administration leads to liver cirrhosis and www.prkm.co.uk tumours and it has been reported to inhibit protein synthesis at a concentration of 20 mg/l00g body wt [11,12]. Various methods such as, amperometric or coulometric titration [13][14][15], redox reactions [16,17], anodisation of mercury [18], and anodic voltammetry of TAM and its amperometric determination at boron-doped diamoned electrode [10] has been used for the determination of TAM in different samples. The electrochemical oxidation of o-diphenols (catechol) has been described [19] and has shown that these compounds can be oxidised to o-quinones under a quasireversible process.…”
