OrganoPhosphonate Test Kit (0-20 ppm)

Description

PRODUCT INFORMATION FLYER

BACKGROUND OF THE TEST:

Organophosphates (also known as Phosphonates and Phosphonic Acids) are widely used for cooling water corrosion and scale control applications and in other industrial applications as well. As a result, residuals of the same are maintained in the system, making it necessary to determine the phosphonates in such water samples. Nuclotrasis offers user friendly test method with ease of handling the relevant reagents and other equipments used in the analysis. For determination of phosphonates in industrial water, this test relies on volumetric titration between sample phosphonates residuals in sample as titrand and standard Thorium Nitrate Solution as titrant while the required reagents are used through easy handling glassware.

REAGENTS/EQUIPMENTS/APPARATUS:

• Provided 5 mL & 10 mL marked glass vial (Item Code: 02-01)

• NUCLOTRASIS PHOSPHONATE-I TEST INDICATOR SOLUTION (Item Code: 01-15-1)

• NUCLOTRASIS PHOSPHONATE-II TEST REAGENT (Item Code: 01-15-2)

• NUCLOTRASIS PHOSPHONATE-III TITRANT SOLUTION (Item Code: 01-15-3)

SAMPLE COLLECTION & PREPARATION:

• Make sure to immediately analyze the sample after collection of sample.

• Ensure to collect sample in a suitable and designated bottle for a specific sample.

• Ensure to conduct this test at room temperatures.

TEST PROCEDURE:

1. Use the provided glass vial (Item Code: 02-01) for sample analysis and rinse the vial by sample to be analyzed. 2. Then take sample to 10 mL mark in the vial.

3. Then add three (3) drops of NUCLOTRASIS PHOSPHONATE-I TEST INDICATOR SOLUTION (Item Code: 01-15-1). The solution will turn purple upon addition of indicator.

4. Then drop wise add NUCLOTRASIS PHOSPHONATE-II TEST REAGENT (Item Code: 01-15-2) until sample color changes from purple to green.

5. Upon green color solution development, now start adding NUCLOTRASIS PHOSPHONATE-III TITRANT SOLUTION (Item Code: 01-15-3) drop wise with gentle mixing and while counting the number of drops added (N) until the pink color appears.

6. Note the number of drops added (N) and calculate the result from formula below:

ORGANOPHOSPHATE (mg/L) = N-2

NOTE: For most accurate results, the test procedure should be run on a blank sample of Phosphonate-free distilled water or M.UP water. This result should be subtracted from the reading obtained in Step 5. In this case, step-6 will not be required and final result will be considered as:

ORGANOPHOSPHATE (mg/L) = No of drops in sample – No of drops in blank
