Test 6-69 06.16
NANOCOLOR® Nitrite 4

طريقو:

Photometric determination with sulfanilamide and N-(1-naphthyl)ethylenediamine

رينج: 0.1–4.0 mg/L NO2-N 0.3–13.0 mg/L NO-
موج جي ڊيگهه (HW = 5-12 nm): 540 nm  
رد عمل جو وقت: 15 منٽ (900 سيڪنڊ)  
رد عمل جي درجه حرارت: 20-25 ° C  

reagent سيٽ جو مواد:

20 ٽيسٽ ٽيوب نائيٽائٽ 4

1 x 100 mL Nitrite A

خطري جي خبرداري:

This tube test does not contain any harmful substances which must be specially labelled as hazardous.

Preliminary tests:

جيڪڏهن ڪنسنٽريشن جي شدت جي ترتيب ۾ جيئنample is not known, a preliminary test with QUANTOFIX® Nitrite (1–80 mg/L NO2 –, REF 913 11) rapidly gives this information. From the order of magnitude the required dilution can be calculated and prepared directly.

مداخلت:

Free chlorine, organic colloids and humic acids can cause interferences.

The following ions will not interfere:

< 1000 mg/L Ca2+, Cr(III), Cu2+، في3+، ايم جي2+، ايم اين2+, Ni2+، زن2+ڪل - , NO3 - , PO4 3-, SO4 2-

< 10 mg/L Cr(VI)

This method can be applied also for the analysis of sea water.

نوٽ:

For removal of emulsions, turbidities and colour prior to the test, e.g. for nitrite in cooling lubricants, seepage water from waste deposits etc., use Reagents for sample preparation by clarification precipitation (REF 918 937).

Analytical quality control:

NANOCONTROL Nitrite (REF 925 68)

Dilute 100+ addition solution with distilled water (1+1): 2.1 mg/L NO2-N
Confidence interval: 1.9–2.3 mg/L NO2-N

حوالو:

German standard methods for the examination of water, waste water and sludge (DIN EN 26 777-D10)
