Scope9.1 This method covers the determination of manganese incompositions from 0.01 % to 5.00 %.10. Summary of Method10.1 Manganous ions are oxidized t
33、o permanganate ions bytreatment with periodate. Tungsten when present at composi-tions greater than 0.5 % is kept in solution with H3PO4.Solutions of the samples are fumed with HClO4so that theeffect of periodate is limited to the oxidation of manganese.Spectrophotometric measurement is made at appr
34、oximately545 nm.11. Composition Range11.1 The recommended composition range is 0.15 mg 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 “narr
35、ow-band” instrument. The composition 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.12. Stability of Color12.1 The color is stable
36、 for at least 24 h.13. Interferences13.1 HClO4treatment, which is used in the procedure,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 metap
37、eriodate ion, the followingprecautions must be observed when filter spectrophotometersare used: Select a filter with maximum transmittance between545 nm and 565 nm.The filter must transmit not more than 5 %of its maximum at a wavelength shorter than 530 nm. The bandwidth of the filter should be less
38、 than 30 nm when measured at50 % of its maximum transmittance. Similar restrictions applywith respect to the wavelength region employed when other“wide-band” instruments are used.13.2 The spectral transmittance curve of permanganate ionsexhibits two useful minima, one at approximately 526 nm, andthe
39、 other at 545 nm. The latter is recommended when a“narrow-band” spectrophotometer is used.13.3 Tungsten, when present in amounts of more than 0.5 %interferes by producing a turbidity in the final solution. Aspecial procedure is provided for use with samples containingmore than 0.5 % tungsten which e
40、liminates the problem bypreventing the precipitation of the tungsten.14. Reagents14.1 Manganese, Standard Solution (1 mL = 0.032 mgMn)Transfer the equivalent of 0.4000 g of assayed, high-purity manganese (purity: 99.99 % minimum), to a 500-mLvolumetric flask and dissolve in 20 mL of HNO3by heating.C
41、ool, dilute to volume, and mix. Using a pipet, transfer 20 mLto a 500-mL volumetric flask, dilute to volume, and mix.14.2 Nitric-Phosphoric Acid MixtureCautiously, whilestirring, add 100 mL of HNO3and 400 mL of H3PO4to 400mL of water. Cool, dilute to 1 L, and mix. Prepare fresh asneeded.14.3 Potassi
42、um Metaperiodate Solution (7.5 g/L)Dissolve7.5 g of potassium metaperiodate (KIO4) in 200 mL of hotHNO3(1 + 1), add 400 mL of H3PO4, cool, dilute to 1 L, andmix.14.4 Water, Pretreated with MetaperiodateAdd 20 mL ofKIO4solution to 1 L of water, mix, heat at not less than 90Cfor 20 min to 30 min, and
43、cool. Use this water to dilutesolutions to volume that have been treated with KIO4solutionto oxidize manganese, and thus avoid reduction of permangan-ate ions by any reducing agents in the untreated water.CautionAvoid the use of this water for other purposes.15. Preparation of Calibration Curve15.1
44、Calibration SolutionsUsing pipets, transfer 5 mL, 10mL, 15 mL, 20 mL, and 25 mLof manganese standard solution(1 mL = 0.032 mg Mn) to 50-mL borosilicate glass volumetricflasks, and if necessary, dilute to approximately 25 mL.Proceed as directed in 15.3.15.2 Reference SolutionTransfer approximately 25
45、 mL ofwater to a 50-mL borosilicate glass volumetric flask. Proceedas directed in 15.3.15.3 Color DevelopmentAdd 10 mL of KIO4solution,and heat the solutions at not less than 90C for 20 min to 30min (Note 2). Cool, dilute to volume with pretreated water, andmix.NOTE 2Immersing the flasks in a boilin
46、g water bath is a preferredmeans of heating them for the specified period to ensure complete colordevelopment.15.4 Spectrophotometry:15.4.1 Multiple-Cell SpectrophotometerMeasure the cellcorrection using the Reference Solution (15.2) in absorptioncells with a 1-cm light path and using a light band c
47、entered atE353 143approximately 545 nm. Using the test cell, take the spectro-photometric readings of the calibration solutions versus theReference Solution (15.2).15.4.2 Single-Cell SpectrophotometerTransfer a suitableportion of the Reference Solution (15.2) to an absorption cellwith a 1-cm light p
48、ath and adjust the spectrophotometer to theinitial setting, using a light band centered at approximately 545nm. While maintaining this adjustment, take the spectrophoto-metric readings of the calibration solutions.15.5 Calibration CurveFollow the instrument manufac-turers instructions for generating
49、 the calibration curve.16.
