M T Valentini Ganzerli et al.
Analytical chemistry, 71(1), 162-166 (1999-01-28)
Radium analysis is carried out by batch adsorption from natural waters on basic lead rhodizonate supported on charcoal, LERHO, starting from 2-L samples. 133Ba is added to allow the measurement of the overall chemical yield by gamma counting. Radium is

The metal distribution within mycorrhizal and nonmycorrhizal roots of Epipactis atrorubens collected from zinc mine tailings and an area rich in heavy metal ores (both located in southern Poland) was investigated. The tailings, consisting of post-flotation material, were characterised by
Statistical analysis of titration data.

A J Chaplin et al.
Histochemistry, 79(1), 111-116 (1983-01-01)
The histochemistry of barium was investigated with particular reference to the use of sodium rhodizonate. It was found that not all batches of sodium rhodizonate were able to effect satisfactory visualisation of barium deposits. None of the other histological parameters
The photochemistry of the rhodizonate dianion in aqueous solution.
Zhao B and Back MH.

Daniele Gibelli et al.
Journal of forensic sciences, 55(4), 1092-1097 (2010-04-14)
Very little literature exists on gunshot wounds on decomposed material. In this study, seven pig heads underwent a shooting test. Entrance wounds from the first head underwent neutron activation analysis (NAA) and histological testing immediately after the firing test; the
Resonance Raman spectroscopy of rhodizonates: Evidence of low-energy transitions in the solid state.
Goncalves NS and Santos PS.
Journal of Raman Spectroscopy, 26(5), 363-372 (1995)
Radiochemical determination of plutonium in urine.

S P Dolan
Journal of AOAC International, 77(3), 718-722 (1994-05-01)
A rapid abrasion test (RAT) was developed for screening ceramicware for Pb. A Pb-sensitive chromogen (rhodizonic acid) reacts to form a persistent colored complex, indicating the presence of Pb. RAT takes 2-5 min to complete; a positive test is easily
M P Van Damme et al.
Analytical biochemistry, 204(2), 250-257 (1992-08-01)
A colloid titration technique has been used to determine the sulfate and carboxylate content of various glycosaminoglycans and has been validated by comparing the results with data obtained using well-established techniques. The method has been applied to the measurement of
Harun Tugcu et al.
The American journal of forensic medicine and pathology, 27(4), 296-299 (2006-11-30)
It is important to investigate the clothing, as well as the body, to determine the range of fire of entry wounds in firearm injuries. Clothing can affect the amount of gunshot residues (GSR) reaching the body and their distribution. The
W Marty et al.
International journal of legal medicine, 116(1), 1-4 (2002-04-02)
The histological staining technique using rhodizonate is also effective for the determination of the firing distance by examining the distribution and intensity of the staining reaction. The differentiation between absolute close-range shots and long-range shots is generally possible without any
Fatma Gorbel et al.
Comptes rendus biologies, 325(9), 927-940 (2002-12-17)
This study deals with the impact of chronic exposure to lead on male and female fertility in rats. Male and female rats (3 months old) were fed on commercial tablets (SICO, Sfax). For drinking, some rats were given distilled water
Dipotassium rhodizonate.
Cowan JA and Howard JAK.
Acta Crystallographica Section E, Structure Reports Online, 60(4), 511-513 (2004)
A spectrophotometric determination of sulfate ion and its application in studies of substrate purity and of aryl sulfatase A kinetics.
A Waheed et al.

J C Stockert et al.
Acta histochemica, 101(4), 397-408 (1999-12-28)
Barium ions precipitate inorganic as well as organic sulfate compounds and they can be detected by a reaction with sodium rhodizonate. In this work, we describe the use of a barium method for the selective demonstration of sulfated glycosaminoglycans in
Analysis of sulfate in complex carbohydrates.
L J Silvestri et al.

R Zoja et al.
Biotechnic & histochemistry : official publication of the Biological Stain Commission, 81(4-6), 151-156 (2006-11-30)
We report a staining method for cadaveric tissue using sodium rhodizonate as a skin marker for gunshot residues and a counterstain for the surrounding connective tissue. We studied six well preserved subjects who had died of close range gunshot injury.
