기능
발색시약이 들어있는 비닐튜브에 물샘플을 넣고, 지정시간이 지난 후 표준색과 비교하는 방법으로 수질을 검사하는 쉽고 편리한 수질 검사용 팩입니다.PH조정등 비색적정에 필요한 전처리 과정을 최대한 줄여 누구라도 쉽게 측정할 수 있도록 고안하였습니다.측정결과를 5분안에 알수 있습니다.(일부항목제외),분석용 시험지에 비해 좀더 낮은 농도까지 측정할 수 있다.

Cautions

1. The Iron (Divalent) (Low range) PACKTEST allows only to measure divalent iron ion Fe2+. If you

wish to measure total iron fraction including suspending particles of a sample, for example:

“rusty water”, we recommend to process samples with sulfuric acid before to use the Iron

PACKTEST WAK- Fe.

2. Adjust a pH out of the range 5 - 9 with diluted sulfuric acid or sodium hydroxide solution.

3. Ensure that PACKTEST tube is filled up to the half.

4. Partially undissolved reagent will not affect the measurement.

5. Keep sample temperature in the range 15 - 40°C. Lower temperature necessitates longer

reaction time.

6. Read the test under a daylight type lamp.

 

Interferences

Standard colors were determined from standard solutions. However, coexisting substances will cause

inaccurate results. The list below reports ion concentrations under which ones interferences are

insignificant:

< 1000 mg/L : As3+, B3+, Ba2+, Ca2+, Cl-, Mg2+, Na+, NH4

+, NO3

-, SO4

2-, Phenol

< 500 mg/L : F-, I-, K+

< 250 mg/L : Mo6+, NO2

-

< 100 mg/L : Pb2+

< 50 mg/L : Cr3+, Mn2+

< 20 mg/L : Cd2+, PO4

3-, Zn2+

< 10 mg/L : Cr6+

< 5 mg/L : CN-, Ni2+, Residual chlorine

< 2 mg/L : Co2+

< 1 mg/L : Al3+, Sn2+

sub-ppm level: Cu2+

The Iron (Divalent) (Low range) PACKTEST is not suitable for sea water samples.
