Tuaslagán copair caighdeánach oibritheach (10 ?g Cu/ml) arna ullmhú tríd an tuaslagán caighdeánach (3.8) a chaolú 1 + 9 le huisce agus tríd an tuaslagán a fhaightear a chaolú 1 + 9le huisce.
Working standard copper solution (10 µg Cu/ml) prepared by diluting the standard solution (3.8) 1 + 9 with water and then diluting the resulting solution 1 + 9 with water.
Chun na himoibreáin agus na tuaslagáin anailíseacha a ullmhú úsáid uisce atá saor ó na caitiain atá le cinneadh, a gheofar trí uisce a dhriogadh faoi dhó i ngloine bórósileacáite nó i stil ghrianchloiche nó trína chóireáil faoi dhó ar roisín malartaithe iarainn.
For preparation of the reagents and analytical solutions use water free from the cations to be determined, obtained either by double distilling water in a borosilicate glass or quartz still or by double treatment on ion exchange resin.
(solution)
The calibration solution "0" must not be used as the blank.
Ná húsáidtear an tuaslagán calabraithe 'O' mar thuaslagán bán.
Tóg 20 ml den tuaslagán forshnámhach agus coigeartaigh an pH go 6.5 le tuaslagán hiodrocsaíd sóidiam 1 N (4.8) agus an tuaslagán bróimicréasóil chorcra (4.9) mar tháscaire.
Take 20 m1 of the supernatant solution and adjust the pH to 6.5 by means of 1 N sodium hydroxide solution (4.8) with the bromocresol purple solution (4.9) as indicator.
Tuaslagán copair caighdeánach oibritheach (100?g Cu/ml) arna ullmhú tríd an tuaslagán caighdeánach (3.8) a chaolú 1 + 9 le huisce agus tríd an tuaslagán a fhaightear a chaolú 1 + 9 1e huisce.
