Photometric measurement is made at approxi-mately 545 nm.10. Concentration Range1

33、0.1 The recommended concentration range is 0.15 to 0.8mg of manganese per 50 mL of solution, using a 1-cm cell (seeNote 1) and a spectrophotometer with a band width of 10 nmor less.NOTE 1This method has been written for cells having a 1-cm lightpath and a “narrow-band” instrument. The concentration

34、range dependsupon band width and spectral region used as well as cell optical pathlength. Cells having other dimensions may be used, provided suitableadjustments can be made in the amounts of sample and reagents used.11. Stability of Color11.1 The color is stable for at least 24 h.12. Interferences1

35、2.1 Perchloric acid treatment, which is used in the proce-dure, yields solutions which can be highly colored due to thepresence of Cr (VI) ions.Although these ions and other coloredions in the sample solution undergo no further change in colorquality upon treatment with metaperiodate ion, the follow

36、ingprecautions must be observed when filter photometers are used:Select a filter with maximum transmittance between 545 and565 nm. The filter must transmit not more than 5 % of itsmaximum at a wavelength shorter than 530 nm. The bandwidth of the filter should be less than 30 nm when measured at50 %

37、of its maximum transmittance. Similar restrictions applywith respect to the wavelength region employed when other“wide-band” instruments are used.12.2 The spectral transmittance curve of permanganate ionsexhibits two useful minima, one at approximately 526 nm, andthe other at 545 nm. The latter is r

38、ecommended when a“narrow-band” spectrophotometer is used.12.3 Tungsten, when present in amounts of more than 0.5 %interferes by producing a turbidity in the final solution.
