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.

Range:0.3, 0.5, 1, 2, 5, 10mg/l

Reaction Time:2min

Method:Nioxime

Cautions

1. The Nickel(DPM) PACKTEST allows to measure dissolved Ni2+ ions concentration. If you wish to

measure total nickel fraction including suspended particles, you must process samples in order

to dissolve solid phases.

2. The normal pH range is 4 - 9. If necessary, adjust the pH with diluted sulfuric acid or sodium

hydroxide solution.

3. The reaction color becomes stronger than 10mg/L of standard color when the nickel standard

solution is 100mg/L.

When the standard solution is higher than 200mg/L, a red precipitate will occur, and the reaction

color becomes colorless.

If you suspect a high concentration, make a dilution of your sample.

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

5. Partially undissolved reagent will not affect the measurement.

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

reaction time.

7. Read the test under a daylight type lamp.

8. Put the line back into the aperture after use to prevent reagent spilt.

 

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:

≤ 500 mg/L : Residual Chlorine

≤ 100 mg/L : Cr3+

≤ 50 mg/L : Fe3+

≤ 10 mg/L : Co2+, Cr6+
