“…Methylene blue forms an insoluble complex with perchlorate; the loss of methylene blue from the supernatant is determined spectrophotometrically (Nabar and Ramachandran, 1959). The neocuproine-cuprous ion complex also has been used to extract perchlorate into ethyl acetate; the bis(neocuproine)cuprous perchlorate species has a visible absorption spectrum (λ max = 456 nm) or, alternatively, the copper content may be determined by atomic absorption photometry (λ = 324.7 nm) (Collinson and Boltz, 1968).…”

Abstract:Since the discovery of perchlorate in the ground and surface waters of several western states, there has been increasing interest in the health effects resulting from chronic exposure to low (parts per billion [ppb]) levels. With this concern has come a need to investigate technologies that might be used to remediate contaminated sites or to treat contaminated water to make it safe for drinking. Possible technologies include physical separation (precipitation, anion exchange, reverse osmosis, and electrodialysis), chemical and electrochemical reduction, and biological or biochemical reduction. A fairly unique combination of chemical and physical properties of perchlorate poses challenges to its analysis and reduction in the environment or in drinking water. The implications of these properties are discussed in terms of remediative or treatment strategies. Recent developments are also covered.

“…To estimate the concentration of ClO À 4 in the tested solution, two stock solutions containing 0.10 M NaCl, 0.80 and 0.40 mM NaClO 4 of pH 5.7 were treated using the same operation procedure as described above. The experimental procedure of the colorimetric method for the measurement of perchlorate was described in detail elsewhere by Nabar and Ramachandran [25]. The PANOA film thickness used for this experiment was controlled by the charge consumed in the electrolysis, which was 5 C in this case.…”

The lithium and sodium perchlorate coordination compounds with hexamethylenetetramine of general formulas:and [Na(ClO 4 ) (H 2 O)(hmta)] n (2) have been synthesized, characterised by elemental and thermal analysis, IR spectroscopy and X-ray crystallography. The compound 2 is a rare three dimensional hybrid compound. The obtained compounds are air stable at room temperature and well soluble in water. As a result of the different electronic properties of the ions, the compounds differ considerably in the molecular structure and consequently in the properties. The studied compounds exhibit opposite placement of both hmta molecules and perchlorate ions: in an outer and inner coordination sphere, respectively, for 1 and 2. The thermal and spectroscopic properties were correlated with the studied compounds molecular structure. -and [Na(ClO 4 ) (H 2 O)(hmta)] n }, of which one is a rare three dimensional hybrid compound, have been synthesized and characterised by: elemental and thermal analysis, IR spectroscopy and X-ray crystallography.
