Radiolysis of solutions of tetrazolium salts

Abstract

Published data on radiolysis of liquid (mainly aqueous, water ± alcohol and alcoholic) and solid [mainly in poly(vinyl alcohol)] solutions of tetrazolium salts are generalised. The mechanism of radiolytic transformations of these compounds is discussed. Their application in dosimetry of ionising radiation is considered in detail. The bibliography includes 60 references.

Dosimetry characterization of tetrazolium violet-polyvinylalcohol films

“…Further reduction of the primary radiolysis product formazan may result in the formation of hydrazine as suggested by Pikaev and Kriminskaya (1998). The effect of TV salt concentration on the response of the dosimeter film was investigated by preparing films made of aqueous air-saturated solutions containing different concentrations (0.1-2 mmol dm À3 ) of TV.…”

“…One of the most widely studied tetrazolium salts is the monotetrazolium 2,3,5-triphenyl-tetrazolium chloride (TTC), which was investigated both in solutions and in films. The film systems were suggested for dosimetry purposes (0.1-100 kGy) in gelatine, polyvinylalcohol (PVA), polyvinylacetate and polyvinylpyrrolidone (Pikaev and Kriminskaya, 1998). Proposed application fields involve radiology, radiobiology (Gierlach and Krebs, 1949) and radiation processing (Kova´cs et al, 1996).…”

“…Tetrazolium blue containing films have shown significant post irradiation stability compared to TTC and found, therefore, application as dosimeters and dose indicators in radiation processing (Pikaev and Kriminskaya, 1998).…”

Pulse radiolysis of tetrazolium violet in aqueous and aqueous-alcoholic solutions under oxidative and reductive conditions

“…Several members, mono-and ditetrazolium salts of the tetrazolium family, have been investigated in solutions or in solid state for characterization as dosimeters (Ková cs et al, 1996(Ková cs et al, , 1999bKriminskaya et al, 1987bKriminskaya et al, , 1992Pikaev and Kriminskaya, 1998). In a few cases mechanistic studies were also performed using ESR spectroscopy at low temperatures (Kriminskaya et al, 1987a(Kriminskaya et al, , 1991.…”

A 2:2:2 Complex of Vanadium(V) with 4-(2-Thiazolylazo)orcinol and 2,3,5-Triphenyl-2H-Tetrazolium Chloride

“…Scarce information about the binary V(V)-TAO complex in water-ethanol medium has been provided by Shalamova. 16 TTC was selected for the present study because of its high application potential [17][18][19][20] and recent interest to its ion-associates. 21 .…”
